Sarah Price powder sand, sand Sarah, Bandung Metallurgical Materials

 Low thermal expansion, thermal expansion coefficient of less than chrome ore and other special sand Sarah same price pink sand, so the casting of high dimensional accuracy, less cracking and surface defects, casting yield. Good resistance to crushing, sand casting treasure good compactness, high strength LFC with Sarah sand price, even if repeated use of renewable rarely broken, reducing the casting process dust pollution production environment, and good regeneration Sarah sand powder reduce industrial waste emissions, environmentally friendly. Fire resistance is good, the main ingredient is aluminum, so good fire resistance. Refractoriness ≥1790 ℃ to meet the cast of various metals and alloys. It is understood that before using sand casting industry Sarah about since the early 1960s has been using the chromite sand. So what are the advantages chromite sand it has long been used in the foundry industry as well? Chromite sand is obtained by crushing the chromite sand. Pure chromite formula FeCr2O4, containing Cr2O3 67.9%. In fact, chromite composition is very complex, and its chemical formula can be written RO · R'2O3.
