Characteristic

Platinum cobalt alloy is a binary alloy based on platinum. At high temperature, platinum and cobalt can be intersoluble indefinitely, its solid solution is a face-centered cubic lattice, slowly cooled to 833℃, the alloy began to orderly transformation. The typical alloy is PtCo23.3, which has strong magnetism, high magnetic stability and magnetic isotropy. Chemical corrosion resistance is very good, potassium hydroxide and hot concentrated sulfuric acid are not corrosion.

Application

It is mainly used for aerospace, navigation, aviation instrument, measuring instrument, electronic clock, magnetron, etc.
