Services

From powder to packed pallet — one supplier for tungsten, molybdenum and specialty copper alloys.

ELKNVEA is a manufacturer and exporter of tungsten, molybdenum and copper alloy materials, working from our base in Dongguan, Guangdong. Sintering, infiltration, machining, inspection and packing are all carried out in-house, so composition, density and tolerances stay under one roof.

Typical applications include resistance welding electrodes, EDM electrodes, heat sinks and thermal spreaders, vacuum furnace fixtures, radiation shielding and high-density counterweights. Send us your drawing or specification and we will quote grade, tolerance and lead time in one reply.
