About Kanthal APM

Sandvik established production line in China in 1990s and abandoned it later, we developed the Kanthal replacement products basing on this production line. Our Kanthal replacement products are produced with the same technique of the original Kanthal products. HJ407’s is the best one, its properties are equivalent to Kanthal APM, much better than Kanthal A-1; but its price is only about$40/kg~$60/kg depending on product specification. We can provide free sample for testing. We also have another grade that can be used as Kanthal A1’s Replacement. For more information, please click here.

HJ407(Kanthal APM Replacement) Key Features:
1. Low tendency to ageing and low resistance change
2. Small change in resistivity
3. High creep resistance
4. Excellent surface oxidization properties
5. Excellent for high temperature heating, up to 1420°C

HJ407(Kanthal APM Replacement) takes refined master alloy as raw material, uses powder metallurgy technology to manufacture alloy ingots, and is manufactured by special cold and hot processing and heat treatment process. The product has the advantages of strong oxidation resistance, good corrosion resistance at high temperature, small creep of electro-thermal components, long service life at high temperature and small change of resistance. HJ407 is suitable for high temperature application (max1420 °C), high power density, corrosive atmosphere, carbon atmosphere and other working environments.
HJ407 can be used in ceramic kilns, high temperature heat treatment furnaces, laboratory furnaces, electronic industrial furnaces and diffusion furnaces.
