White Fused Alumina High Temperature Resistant
The WFA is the main raw material for the production of unshaped and shaped refractory materials. Commonly used in ladle castables, iron runner materials, refractory gunning mix materials and other monolithic refractory products.

Benefits
White fused alumina is a high-temperature resistant material. It is made by fusing high-purity alumina powder in an electric arc furnace at a temperature of over 2000°C. This process creates a very hard and dense material with high temperature resistance.
White fused alumina has a melting point of around 2250°C and can withstand temperatures up to 1900°C. It also has excellent thermal shock resistance, meaning it can withstand sudden changes in temperature without cracking or breaking.
Because of its high temperature resistance and hardness, white fused alumina is commonly used in applications such as refractory materials, abrasive tools, and ceramic materials. It is also used in the production of high-temperature ceramics and as a filler in epoxy resins to increase their thermal conductivity.

Packing
Bags: WFA may be packed in bags made of different materials, such as paper, plastic, or woven polypropylene. The bags may come in different sizes and weights, depending on the quantity of WFA being shipped or stored.
Drums: WFA may also be packed in drums made of steel or plastic. Drums offer greater protection against moisture, dust, and other environmental factors that may affect the quality of the material.
Bulk bags: For larger quantities of WFA, bulk bags made of woven polypropylene may be used. These bags can hold several tons of material and are often transported on pallets for ease of handling.
Custom packaging: Depending on the specific requirements of the customer, WFA may be packed in custom-made packaging such as vacuum-sealed bags, moisture-resistant containers, or other specialized packaging.
