Steel Couplings are the most commonly used and manufactured. The exact type of steel used varies depending on the machine process but generally low-carbon steel is used, including materials such as 1215, 1045, and 1026.

Stainless Steel Couplings are used primarily in applications where component wash down is frequent such as food processing, pharmaceutical or marine applications. Climax manufactures with austenitic type 303 stainless steel that meets FDA guidelines.

Aluminum Couplings are lighter, have the non-magnetic properties of aluminum desirable for many applications, and have a bright gleaming finish that is highly suitable for applications with high visibility.

Climax does not manufacture with powdered or sintered steel because it makes a poor quality collar and cannot be welded. In sintered set screw collars, the threads tend to be weak and not uniform in performance.
