If oxygen is excluded from the wraps of coiled product, from the inner surfaces of stacked flat products, or from the faying surfaces of extruded products, and should moisture be permitted to enter th [..]

One of several systems that serve to measure a metal’s resistance to mechanical indentation. There are other hardness testing devices, but the Brinell equipment provides the readings most commonly fou [..]

Proprietary solutions, usually of a chromate or phosphate variety, which, when applied to a clean aluminum surface will serve to increase the metal’s resistance to corrosion and provide a good base fo [..]

The deterioration of material due to its reaction to its environment. Depending upon the type of corrosive conditions, the deterioration may be staining, pitting, flaking or, in very severe cases, fra [..]

One of the mechanical properties of aluminum, i.e., the ability of the metal to stretch, or elongate, when it is subjected to an applied stress. The distance the metal will stretch from the point wher [..]

A cast form of the metal that is suitable for remelting or fabricating. The ingot may take the form of rolling ingot, extrusion ingot, forging ingot or remelt ingot. The size and shape of the cast pro [..]

Those properties associated with the material’s reaction when force is applied, or that involve the relationship between stress and strain. This would include tensile properties, modulus of elasticity [..]

Another of the methods used to determine a metal’s resistance to indentation. Rockwell equipment is more widely used than the Brinell equipment and many more testers of aluminum will refer to the Rock [..]

A high-speed method of cutting sheet in coiled form to narrower width coils. Although there are flat sheet slitters in existence, most machines will only accommodate coiled products. Two circular kniv [..]

Another common term to describe mechanical strength. This metal property is expressed in thousands of pounds per square inch and denotes how much stress can be gradually applied to the metal before it [..]
