Pùdar carbide tungsten a thilgeil

Tha Pùdar Cast Tungsten Carbide (CTC) air a dhèanamh de bhith a’ leaghadh agus a’ pronnadh W agus WC agus tha e na ghràinean dorcha glas neo-riaghailteach le puing leaghaidh àrd (2525 ℃), cruas àrd (≥ 2000 HV0.1), agus sàr chaitheamh caitheamh.

Bithear a’ cleachdadh CTC gus pùdar PDC matrix bits ullachadh, pùdar Plasma Arc Welding (PTAW), stuthan tàthaidh spraeraidh, electrodan dìon-caitheamh carbide saimeant (uèir), msaa. airson mèinnearachd, ola & gas, Meatailteachd, innealan togail, innealan àiteachais, agus gnìomhachasan stàilinn.
