METAL COMPOSITE STRIPS - CONTACT MATERIALS
Metal Composite Strip Metal Contact Composite Strip is an advanced production technology that seeks to incorporate electrical contact on different metal material strips. The primary advantage of combining different metals is reflected in material cost saving which seeks to replace certain area with less expensive metal material without sacrificing functionality. Another advantage of using composite strip is the flexibility to increase conductivity on specific contact area without additional electrical contact components. Realized through multiple processes, metal composite strip is available in 2 variation, namely Overlay Composite and Recessed Composite.
