Tendency of a material to oxidize

Tendency of a material to oxidize

Tendency of a material to oxidize

(OP)
I need to use a metallic powder as a base metal in a brazing process.  I was using copper, but it oxidizes too much at high temperatures(in the range of 800C).  How can I predict what material will have a slower oxidation rate or just less oxidation?  Also, is there an oxidation activation temperature range?
 

RE: Tendency of a material to oxidize

I would try Lucas Milhaupt on this.  

The standard industry approach is to use copper with a flux, atmosphere or vacuum.   A good braze joint has both mechanical and chemical joining (it forms an intermetallic between the braze alloy and the base metal).
