H13 and Cobalt Based Alloy Heat Extrusion Die Cores

Product Description

Trade
The Cobalt Chrome Alloy hot extrusion die is designed to extrude the copper, aluminum bars, rods and other profiled
parts, the points are in high high-temperature environment. The process must be a hot extrusion. The Cobalt Chrome Alloy
material will help you to solve he high temperature and wear resistance issue. For more details please
check below.

Product Introduction:

(1) Cobalt alloy is a range of cobalt-chromium alloys designed for wear resistance.

(2) It is a completely non-magnetic and corrosion-resistant cobalt alloy.

(3) There are a number of Cobalt Chrome Alloys with various compositions optimized for different uses.
(4) Some are formulated to maximize combinations of wear resistance, corrosion resistance,
or ability to withstand extreme temperatures.
