The Meehanite Metal Corporation has been in business for overseventy years, developing a family of high performance cast ductileand flake irons described in the following sections. This handbook

of Meehanite Metals has been prepared fordesigners, engineers and purchasing executiveswho strive to improve product performance andreduce manufacturing costs. It presents themechanical & physical properties of each type of Meehanite Metal in a clear and concise manner in order to aid in the selection of the

particular type of Meehanite® which will most completely meet thebuyer’s requirements.

Meehanite Metals furnish industry with engineering materials ofknown and consistent properties on which casting design can besafely based. They have proved their value the world over from notonly the viewpoint of dependable service, but economy as well.

The following pages outline some of the advantages to be gainedby the use of Meehanite® and explain why this versatile material isso widely recognized and used throughout industry.

To compliment the development of these materials, Meehanitelicenses only qualified foundries to produce these products. Everylicensee is required to undergo a strict training regimen before theyare permitted to produce any grade of Meehanite. Further to this,an ongoing program of auditing is followed, to ensure that the stan-dards required for production are maintained.

If you are interested in obtaining a Meehanite license, you canfind out what is involved and the services we provide by going topage 88 - The Meehanite Connection.
