Aluminum

Pin openings

Metals; Aluminum

A method commonly used for checking wall thickness consistency in a die using pin gauges.

Stretch straightening

Metals; Aluminum

The process of stretching extruded sections beyond the yield strength of the alloy to achieve longitudinal straightness.

Relieving stress

Metals; Aluminum

The reduction of the effects of internal residual stresses by thermal or mechanical means.

Stress

Metals; Aluminum

Force per unit of area. Stress is normally calculated on the basis of the original cross-sectional dimensions. The three kinds of stresses are tensile, compressive, and shear.

Strength/weight ratio

Metals; Aluminum

The relationship between the structural strength of a material and its weight. The strength-to-weight ratio of structural aluminium alloys is about twice that of mild steel.

Structural streak

Metals; Aluminum

A non-uniform appearance on an etched or anodized surface caused by heterogeneities (variabilities) remaining in the metal from the casting, thermal processes or hot working stages of fabrication.
