- Comparison of aluminium and copper
When comparing aluminium and copper with each other, there are a number of differences. Fundamentally the comparison is done by assuming copper as the basis and then creating comparative figures with aluminium.
The first comparison here between aluminium and copper considers both metals having equal cross-sections. In this case density, price and conductance are considered. The results for the same cross-section comparison show that aluminium is cheaper and is only about one-tenth the price of copper. Comparatively, aluminium has a lower density and is characterized by a remarkable conductance.
When comparing a piece aluminium and copper, which both contain the same conductance, the required cross-section of the aluminium is greater in order to achieve the identical conductivity of the copper. Also there is a significant difference in weight. Aluminium’s weight is only half of the copper’s. Moreover aluminium remains very reasonably priced in comparison to copper in spite of its larger cross-section.
- Comparison of AlCunnect and Cupal
Cupal (Manufacturer: VSW Hetzel e.K.) is a composite material made of aluminium and copper, which is plated over the entire surface. Even though AlCunnect and Cupal are bimetals, there are some differences. DODUCO can produce layer thicknesses of up to 0.4” (10mm) for AlCunnect. However, the layer thickness of Cupal is only offered between 0.02” - 0.08” (0.5-2mm). Likewise aluminium copper thickness ratios of Cupal are 30:70 or 20:80. Comparatively AlCunnect’s thickness ratios are individually selectable. In addition to the manufacturing process of overlay plating DODUCO has the know-how of overlap plating of the metals aluminium and copper. The overlap plated clad metal AlCunnect offers further application possibilities for the material combination.
