Ballistic and Hurricane Resistant Aluminum


Isotec uses a 6061-T6 aluminum alloy for our doors and frames in our Safety Entrances™. The 6061 alloy has 64% greater strength to weight ratio, 72% greater tensile strength, and 75% greater shear strength than the 6063-T5 alloy used by others.

Strength to weight is a rather self-defined expression. The 6061 alloy weighs less but is stronger than the 6063 alloy. This strength to weight ratio is reflected in the higher tensile and shear strength ratios of the alloy.

Tensile strength is measured by the maximum stress that a material can withstand while being stretched or pulled before breaking. This is important for our structures, doors, and ballistic glass need to withstand the energy generated by gunfire.

Shear strength . A shear load is a force that tends to produce a sliding failure on a material along a plane that is parallel to the direction of the force. In structural and mechanical engineering, the shear strength of a component is important for designing the dimensions and materials to be used for the manufacture or construction of the component like transom, oversized doors and side walls with glass panels that can weigh more 300 pounds.

Most importantly, the 6061-T6 alloy has a greater ballistic resistance than and “wind load” capacity than 6063-T5.  For those of you who live in hurricane areas, you know the importance of having buildings and structures that can stand up to 150mph plus hurricane force winds.
