Webare sufficient to strain metals beyond the yield point. Molten Metals In industrial applications, low-melting metals such as copper and silver braze alloys, zinc, and aluminum cause problems. As a rule of thumb, low-melting metals attack the higher nickel alloys more readily than low-nickel or ferritic grades. Galling Webcompound. With the low melt point of zinc stearate, this has typically not been a problem. The zinc stearate will melt during molding and be absorbed into the compound without leaving discoloration or defects on the surface of the final molded rubber part. The chemical structure of metallic stearates consists of a very long stable hydrocarbon ...
