W, Mo, TZM, CuW, AgW insert Spot welding electrode

No-ferrous metal(W, Mo, TZM, CuW, AgW) metal and alloy has high melting point. It has excellent proporites for high temperature strength, creep resistance, electron emission. Moreover, tungsten is low coefficient of expansion and the lowest metal vapor pressure. In generally, we adopt powder metallurgy to produce this alloy.

Compare to the NDB and back casting technoloy to bulid the non-defect between the tungsten and copper shank, we use advanced CBT^® technology bonding the shank with the No-ferrous metal tips. Our CBT no-ferrous insert spot welding electrode face material can be tungsten, Lanthanum tungsten, molybdenum, TZM, Silver tungsten. HOSO's electrode can acheive very good working life time and prodcution yeild rate.

HOSO Metal design the electrode especially for the resistance spot welding. For more details refer to our tungstent electrode catalogue. Normally, Our tungsten electrode has two types:

1: pure tungsten electrode

2: tungsten-faced electrode, shank material copper, BeCu, or CuCrlZr.

3: two kinds of join technology between tungsten and copper shank. Which is silver braze and NDB(No defect bonding)
