Kanthal history

Hans Gustav Albert von Kantzow, 1887–1979

The Kanthal® brand is based on the company AB Kanthal® that was founded in 1931 by Hans von Kantzow in Hallstahammar, Sweden. The business idea was to market and further develop his invention - the Kanthal iron-chromium-aluminium (FeCrAl) resistance heating alloy.

The Kanthal® FeCrAl alloy was invented almost by accident. A forgotten sample in a furnace resulted, after years of development work, in a completely new resistance material based on this alloy. After the market introduction in 1931, the Kanthal® alloy outperformed the existing nickel-chromium (NiCr) alloys and Kanthal expanded rapidly on the world market.

In the late 1990s Sandvik became majority shareholder in Kanthal®. Today Kanthal® is the brand for Sandvik's heating technology products and services. The original Kanthal® FeCrAl alloy is still a product in our portfolio, although improved in a number of aspects. It is now part of a complete product range of heating technology products and resistance materials that covers almost all applications and temperatures.
