PRODUCT DESCRIPTION：YONAI Produces Good WFA.
White Fused Aluminum Oxide is a high purity fused aluminum oxide. It achieves its white color as it is lower in impurities than brown or pink fused aluminum oxide. It typically has higher friability than brown fused aluminum oxide. With a Mohs hardness of 9, Aluminum Oxide is a high strength, wear-resistant material possessing a strong ability to resist vigorous chemical attacks (such as acid and alkali) at extreme temperatures. Its high degree of refractoriness, along with its superior electrical insulating properties, dielectric properties, and high melting point make White Fused Aluminum Oxide a desirable material choice for a diverse range of applications.
