About Us

YHM was established in 1979.The main products are Copper Alloy Wires included Brass Wire,Phosphor Bronze Wire, Silicon Bronze Wire, Nickel Silver Wire and EDM Wire.The wire material was metallurgy by advanced technology Upcast( Upward Continuous Casting ) .This technology similar to Semi-Conductors' grain size growth.It made material high purified,grain size uniformed and without joint in jumbo coil .It enhanced the electron transmission,voltage and current stable was used to advantage forEDM Wire products.

Development

2010
Brass mother wire supply for EDM wire re-drawing over 500MT per month.
2009
Brass wire rod C2800(60/40) was succeed by Upward Continuous Casting. The wire is better quality for EDM wire redrawing, this EDM wire been test at AGIE Progress V3 and got very good results.
2005
Zn-coated wire for EDM is succeed for precision cutting. This wire quality is suitable for AGIE EDM machine.
New plant for Phosphor Copper Anode, the quality is succeed in the marketing into PCB ( Printed
Circuit Board) industrial.
