豐泰長期供應White corundum白剛玉、高純度優質白剛玉質量保證

白剛玉是以優質的鋁氧粉為原料，經電熔冶煉而成。它具有顏色潔白、硬度高、韌性低、純度高、自銳性優、磨削力強、發熱量小、效率高、耐酸堿腐蝕、耐高溫、熱穩定性好等特點，它不但是高級的磨料磨具材料，且還是高級研磨、拋光材料等，用它加工制成的磨具，適用於磨削高碳鋼、高速鋼及各種不銹鋼。它還廣泛適用於精密鑄造、鋼鐵耐火、化工耐火、95電瓷、裝飾瓷等特種陶瓷以及日常生活用瓷、軍工、電子等高科技行業。
我公司常年向日本、韓國、歐美等國傢和地區出口白剛玉產品。可以根據用戶需要，提供各種規格白剛玉分段砂、F砂、P砂、微粉等。

With high-quality aluminum oxide powder as raw material, white corundum is formed by the fused smelting. It has the white color, high hardness, toughness, high purity, high efficiency, acid and alkali corrosion, good thermal stability characteristics and many other characteristics. It is not only advanced abrasives materials, but also advanced grinding, polishing materials. It is suitable for grinding hardened alloy steel, high speed steel. Fine-grained flour is also used for precision casting.
Our company exports white corundum products perennially to Japan, Korea, Europe and the United States and other countries and regions. We can offer you all types of white corundum products, such as F sand, P sand, powder and so on.
