The history of Chuetsu Metal Works Co., Ltd., began in the late 1940's, when the fledgling company became successful in supplying TM alloy for bearing cages as one of it's main products.  Through the years Chuetsu has embarked in assiduous research and development to supply products of the highest quality.  As a result of this quality and ingenuity, Chuetsu won the coveted Deming Prize and became ISO 9002 and QS 9000 certified.

Today Chuetsu Metal Works is one of the world's largest manufacturers of copper and copper alloy products. The product line not only encompasses bearing cages but has expanded to include Copper Molds, Synchronizer Rings, Copper Crucibles, Lead-Free Bronze products and much more. Chuetsu is truly an expert partner to serve many various branches of industry.
