Heat Resistant Substrate Zirconia Ceramic Press Switch For
Hydraulic Selector
Product Description
Zirconia Ceramic not only have good feature of high hardness and high wear
resistance,but also is excellent in toughness among fine ceramic
material, so it's commomly used for structural parts and wear
parts. As thermal expansion coefficient is close to the steel, it
is also used to connecte ceramic and steel. Expect coommonly used
in the field of industrial structural parts, Zirconia Ceramic is
also widely used in daily-used ceramic because of its jade-like
texture.
