Gunmetal Ingots

Gunmetal is also an alloy of copper that has diverse industrial applications. These copper alloy ingots from Bright Metals find extensive use in the electrical and sanitary fittings. These durable and dynamic ingots are also used in the making of valves, batteries, radiators, etc.

Besides these superior quality gunmetal ingots, we also offer cast ingots, aluminium ingots and brass ingots. As one of the most trusted gunmetal ingots suppliers and exporters, we conduct on- time supply of other metal alloy products that also include brass coils, alloys for jewellery, brass strips, etc.
