Our Aluminum Square Bar is Suitable for a Range of Different Applications

A key part of diverse metal fabrication projects, aluminum square rod is a flexible option for many challenging situations. Aluminum and its alloys have many advantages over other metals when it comes to functionality. It is extremely resistant to corrosion – a real bonus for surfaces that are going to be exposed to the elements or come into contact with moisture. For example, any marine industry applications. Aluminum is also extremely strong and very lightweight, which is why it is one of the main materials used in the aerospace and aircraft industries. In addition, aluminum has a high level of malleability and ductility, enabling it to be configured into many different shapes. All these properties mean that aluminum square stock is always in demand.

FAQ

Square bar aluminum bar has a tolerance of as close as plus/minus .005” when extrusion saw cutting is used. When band saw cutting is used, the tolerance is +.30/-.000. You can expect your square bar aluminum to have good dimensional accuracy.
The extrusion process is most optimal when the shape is uniform. You can’t get any more uniform than a square, round, or hexagon extrusion. The extrusion process is able to produce more pounds per hour on beefy symmetrical shapes like an Aluminum square bar, as well as consistent grain structure and machinability. To improve ensure the precision of square bar aluminum, Howard Precision Metals only works with the most advanced extruders in the country producing aluminum with e through means of ensuring that only the most cutting-edge technology is used at all times. The square bar aluminum will be heat treated during the extrusion process, to improve its durability.
