Factors to Consider When Evaluating a Metal Supplier for Your Business

When you are embarking on a new major project or even a smaller routine job, you need the right metal supplier to get the work done according to your specifications. Not every metal supplier has the same capabilities. It is important to choose a company you know can provide you with the exact products you need and at high quality. Metals of superior quality are essential for building components and products that have reliability and longevity. If you settle for less with your metal supplier, it could negatively affect the reputation and performance of your business. At Howard Precision Metals, a leader among aluminum suppliers, we serve as a premier provider of aluminum alloy products, including cast aluminum and custom aluminum extrusions.

Below are several factors to consider when choosing a metal supplier:

Your Project’s Timeline

You must know if the supplier can accommodate the estimated timeframe of your full project. Develop a timeline to share with potential metal suppliers, if you don’t have one already. Having a timeline will help eliminate complications and misunderstanding with production and delivery between you and the supplier.

With a structured timeline in place, you will have a plan everyone can follow and an easy way to track how well you are keeping pace with the plan.

The Scale of Your Project

The scale of the project refers to its size and demand. A supplier should know about these aspects of your project before providing you with a quote. Determine the types of materials and shapes you will need for the project. If you end up working with a supplier that is unable to accommodate your order requests or do so within expected timelines, this can negatively impact the production and profits of your business and your relationship with the supplier.

Project Budget

It can be a challenge to obtain a quote from a metal supplier if you don’t have a good understanding of the budget for your project. You may not be able to get the best deal if you don’t know what flexibility you have with your budget. Be sure to create a clear financial picture before you start contacting metal suppliers. Once you know your budget, you can know what to ask for from aluminum plate suppliers and how much room you have to negotiate on pricing for the aluminum products you need.

Supplier’s Reputation and Track Record

The last thing you need as a business owner is to partner with a company with a bad reputation and poor track record. Make sure the supplier you are looking to work with has all of the required certifications and qualifications necessary to legally operate as a metal supplier. Doing so will ensure your business is able to avoid legal issues down the road.

Find the customer satisfaction rating of the supplier if possible. If most of the reviews are positive and there are an abundance of them compared to any negative reviews, then you can have confidence you have a reputable supplier.

Sufficient Workforce

After reviewing the demands and scope of your project, make sure the supplier you intend to contract with has the workforce required to fulfill your orders. Find out the size of the supplier’s team and the certifications and skills they possess. For instance, you may need metal supply professionals with experience in certain services such as creating custom aluminum extrusions. Knowing the capabilities of the staff of a supplier and information about their inventory can give you confidence about hiring them.

Quality and Capabilities

Every business has its own way of measuring quality. You can develop questions to ask prospective suppliers. If you visit the supplier’s facility, learn about what processes and standards they follow, particularly concerning quality control. Make sure their process conforms to what any relevant regulatory agencies require and what you require.

Cast aluminum and aluminum extrusion suppliers should have the capability to handle special orders in-house or in conjunction with one or more trusted partners.

Customer Service

One of the major keys to developing an enduring relationship with a metal supplier is the attentive customer service they provide. As you communicate with the supplier about their process and capabilities, take note of how they communicate and respond to you. Is there one point of contact you have access to or are you being bounced from one person to another. Does the supplier reply quickly to your inquiries or does it take them too long to respond?

If possible, obtain references from the company or find other customers yourself who have used the supplier. Find out from them how the company communicated and served their metal supply needs.

Differences Between Cast and Wrought Aluminum Alloys

Aluminum alloys are categorized into two groups – cast aluminum and wrought aluminum alloy. These designations are based on the type or processing used to create each. At Howard Precision Metals, we are your leader for the supply of cast aluminum alloys used in making cast aluminum plate. You can trust our knowledge, experience, and resources, to help you obtain the quality aluminum cast and wrought products you need for your commercial or industrial applications.

Cast Aluminum Alloys

Cast aluminum alloys have aluminum as the primary metal with other alloying elements added. This group of alloys can be divided into heat-treatable and non-heat treatable cast aluminum alloy. In addition, these alloys have a comparatively low tensile strength, but help create cost-efficient products. The exceptional casting characteristics of this type of aluminum alloy is due to the significant presence of silicon in its composition.

Some of the beneficial characteristics of aluminum alloys that make them ideal as cast aluminum alloys include:

  • Ability to control grain structure
  • Good fluidity
  • Low melting point
  • Ability to strengthen through heat treatment
  • Low solubility of gasses
  • Good surface finish

At the same time, a cast aluminum alloy has some potential negative characteristics. These alloys are susceptible to shrinkage effects due to its high shrinkage characteristics. These alloys, including cast aluminum plate, also possess low ductility and are vulnerable to heat cracking. They also have a high solubility of hydrogen gas.

Wrought Aluminum Alloys

Wrought aluminum alloys also have aluminum as the primary metal. These alloys are used mostly for shaping processes such as extrusion, forging, and rolling. They are both heat-treatable and non-heat-treatable. Wrought alloys of aluminum represents about 85% of all aluminum alloys.

The alloying elements such as silicon, copper, zinc, and magnesium provide a heat-treatable alloy’s initial strength. They can be strengthened further through heat treatment. Non-heat-treatable forms have alloying elements such as silicon, manganese, and magnesium as their initial strength. These alloys can be strengthened further through strain hardening or cold working.

Differences Between Cast and Wrought Aluminum Alloys

Cast aluminum is a type of aluminum alloy with casting characteristics. Wrought aluminum, on the other hand, is ideal for shaping and machining after heat treatment.

Additional differences between these two types of aluminum alloys include:

Percentage of Alloying Elements

Wrought aluminum is an alloy that has been worked on by processes of mechanical working. These can include extrusion, rolling, and forging. On the other hand, cast aluminum is formed by the pouring of heated, molten aluminum in dies or patterns. Cast aluminum has a larger percentage of alloying elements in its constitution. In wrought aluminum, about 85% of its make up is aluminum.

Internal and External Defects

The important difference between wrought and cast aluminum alloys is that wrought aluminum alloys are usually free of external and internal defects, whereas cast aluminum alloys have many external and internal defects.

Melting Point

The melting point of cast aluminum alloy, including cast aluminum plate, is low, which gives it high cost-effectiveness, while the melting point of wrought aluminum alloy is high, giving it low cost-effectiveness.

Tensile Strength

The tensile strength of wrought aluminum alloy is higher than that of cast aluminum alloy.

Thickness

Cast aluminum alloys are typically thicker and heavier, while wrought aluminum alloys may be obtained down to a foil thickness.

Precision

Because of its low tensile strength, cast aluminum alloys achieve high precision due to the numerous external and internal defects. The ability of wrought aluminum to be processed on the other hand, allows it to undergo drilling, milling, grinding, and more, which means it is ideal for dimensional accuracy and precision parts.

Numbering Systems

There are two numbering systems for aluminum alloys. The categorizing of aluminum alloys uses a familiar four-digit number system. This system is used for the classification of wrought aluminum alloys and also a number of cast plates.

On the other hand, the classification for alloys used for the production of cast aluminum parts is different. Although this system also uses four digits, a decimal point is included between the third and fourth digits. Sometimes cast alloys are only given three numbers for their classification because the decimal is often zero.

Cast aluminum alloys offer a wider range of shapes and have a lower price per pound, while wrought aluminum alloy is better for processing with better mechanical properties. High-end applications in the aerospace and aviation fields make use of the surface finishes possible with wrought aluminum alloy.

Due to the different performance capabilities between cast and wrought aluminum alloys, they are used in different applications. Wrought aluminum can be seen in various aspects of the construction and ship building industries, and also for airframes, impellers, engine blades, landing gear parts, and propeller blades. Cast aluminum alloys are used often in the agricultural, automotive, and construction industries, including for pistons and transmissions, cylinder heads, engine boxes, hubs, instrument housings, turbine blades, window fittings, supercharger pumps, and farm equipment.
