Home Products Clad Metals High Strength Aluminum HIGH STRENGTH ALUMINUM REPLACES COSTLY COPPER WITHOUT COMPROMISE High Strength Aluminum (HSA) materials are copper alternatives for electronic components, supporting lightweighting and cost-down initiatives in wiring systems. With the rapid acceptance of aluminum wiring harnesses in vehicles, aluminum technologies are now extending to connector and lead frame solutions enabling 100% aluminum based electrical systems. INCREASE CONDUCTIVITY WHILE REDUCING DENSITY With low cost, low density and yet high strength and high conductivity, High Strength Aluminum provides cost and weight reductions over commonly used brass and bronze base metals. Electrical Conductivity (%IACS) Density (lb/in3) AL6-TX* 43% 0.098 AL2-TX* 30% 0.100 C260 BRASS 28% 0.308 C519 BRONZE 15% 0.319 *HSA-TX temper can be tailored to meet your design requirements. For aluminum connectors, HSA is available with clad or electroplated contact materials. In wire bondable lead frame applications, HSA provides the same high reliability of aluminum inlay. Utilizing heat treated aluminum alloys provided in coil form, HSA copper alternatives are ready for high throughput stamping and forming of components. Aluminum connectors and lead frame materials come semi-finished, with electroplated or clad functional layers. For example, electroplated aluminum connectors may have nickel, tin, silver or gold contact surfaces. The third most abundant element on earth, aluminum offers vast availability and low cost, reducing cost variability in electrical components. In comparison, the cost of copper can be volatile causing large swings in the cost of copper components.
