HIGH STRENGTH ALUMINUM ELECTRICAL MATERIALS FOR COPPER REPLACEMENT


High Strength Aluminum (or HSA) Materials are high performance, low cost, aluminum-based alternatives to common copper alloys used in electrical components.  In connectors and wire bondable lead frames High Strength Aluminum Materials provide cost and weight reductions over brass and bronze alloys without sacrificing strength or conductivity.  Utilizing heat treated aluminum alloys provided in coil form, HSA materials are ready for high throughput stamping and forming of components.


BENEFITS OF HIGH STRENGTH ALUMINUM:

  • Reduce costs by switching from copper
  • Available with clad or electroplated contact materials
  • Same high reliability bond pads as "aluminum inlay"
  • 30% the weight of copper alloys
  • Excellent electrical conductivity
  • Formable for reel-to-reel stamping

* HSA-TX temper can be tailored to meet your design requirements. 

HSA Electrical Materials enable 100% aluminum systems, eliminating the danger of Galvanic Corrosion that is present in mixed copper-aluminum systems. The third most abundant element on earth, aluminum offers vast availability, low costs, and reduced weights of electrical components.    

The Strength and Conductivity of High Strength Aluminum components can exceed those of many brass and bronze alloys that are commonly used in electrical systems.  Lead Frames, Busbars, Electrical Connectors can all benefit from this technology breakthrough.
