BAg-8 Silver brazing ring / wire / rod / strip manufacturer

   72%Ag High Silver Brazing Alloy AWS BAg-8 Welding Sheet/Strip     HUAZHONG HZ-Ag72B silver Brazing Alloy is a eutectic composition of the silver copper system. It is suitable for use in a controlled atmosphere brazing without the use of a paste flux. When molten, HZ-Ag72B is very fluid and may flow out over the work surfaces during some furnace brazing applications. The wetting action on ferrous metals is limited, minimizing its use on carbon steel. Improved wetting observed when furnace brazing of stainless steel with silver copper filler metals. Most applications for this alloy are on copper and nickel based alloys.   Properties : Generally, the joint strength using HZ-Ag72Bsurpasses the strengths of the base metals. Strength is a function ofthe base metals being joined, type of joint, design of joint, joint clearances and brazing procedures. Therecommended maximum operating temperatures for HZ-Ag72B is up to 204°C(continuous service) and 315°C (intermittent service). Where improved corrosion resistance is needed, nickel may be added to the eutectic composition.   Related parameters : AWS A5-8 BAg-8 ASME BAg-8 Chemical Compositions(%):Ag72, Cu28.
