Aluminum industry

Liquid metals are very corrosive and attack equipment or parts that come in contact with them. In some cases, parts operate only for few minutes.

Solutions are required to extend their service life.   Thermal spray coatings offer a range of cost-effective solutions to the industry for liquid metal corrosion. 

Metal 7 has been very active in developing resistant coatings for liquid metals in the last years.  Its location in the province of Quebec where several large aluminum smelters operate, and the presence of the large plant of Aluminerie Alouette only 30 kilometers away from Metal 7, have definitely contributed to this specific effort on development of liquid metal abrasion solutions.

The focus of Metal 7 has been on two main coating families for the liquid metal applications:

1-    Solutions for parts exposed to liquid aluminum;
2-    Solutions for parts exposed to liquid cast iron.
