Meehanite is a trademark for an engineering process to make a range of cast irons produced under specific and carefully controlled conditions to precise internationally recognized specifications. According to the Meehanite Worldwide company, when correctly followed the Meehanite process will produce cast iron with uniform soundness, consistent physical and mechanical properties and dependable performance in service.[1]
When a foundry advertises that it produces "Meehanite" it means that the foundry is licensed by Meehanite Metal Corporation to produce the family of Meehanite irons. The licensing agreement means, according to Meehanite, not only that the foundry is qualified but also that the licensed foundry is certified by audit to meet the required process standards.
The Trademark name is owned by Meehanite Worldwide. Meehanite Worldwide has five franchises: The Meehanite Metal Corp located in Mequon, Wisconsin; The International Meehanite Metal Corp located in Finland; and franchises in Taiwan, South Africa, and Japan.
The Meehanite specifications can be classified into three broad types: High duty flake or gray irons; high duty “nodular” or ductile iron (SG); and a group consisting of special types for applications requiring resistance to heat, wear and corrosion.
Castings made by this method are used extensively to make machine tools, gears, sheaves, cylinder heads, valve bodies, rollers and other highly engineered applications.
