Temper Code - refers to material hardness, our bronze is predominately produced in H04 but can be made in other tempers if required. 

Tensile Strength - Our standard fasteners are manufactured from fastener grade alloys formed from hard drawn wire.  This is an important distinction in the comparative strength of items made from continuous cast material, which does not have the strength and ductility.

Electrical Conductivity - IACS - International Annealed Copper Standard - a unit for measuring electrical conductivity where 100% IACS is assigned to annealed copper at 20°C. 

Electrical conductivity is the primary characteristic that distinguishes copper from other metals. Of the commercially useful metals, copper is only surpassed by silver. But copper alloys have a wide range of conductivity. There are hundreds of copper alloy strip metals from which to choose and some of them have conductivity as low as that of iron.
