Aluminum Die Casting Electrical Tool Parts are a metal forming process in which molten aluminum metal is put under pressure and injected into a die. Aluminum weighs 1/3 of a comparable steel part. The Aluminum Parts would cost less to ship due to the weight and spend less expense than other manufacturing processes.

Aluminum Die Casting Electrical Tool Parts are lightweight alloys that have good corrosion resistance, mechanical properties, high thermal and electrical conductivity and strength at high temperatures. Aluminum alloys possess high dimensional stability for complex shapes and thin walls.

Aluminum Die Casting Electrical Tool Parts are efficient and economical and offers a wide range of durable shapes and components. Little or no machining is required after a part is die casted, because the process provides very close tolerances for even complex shapes. Aluminum Die Castings can also be easily plated or finished. Aluminum Die Casting Electrical Tool Parts are dimensionally stable and heat resistant.
