Our Story
Nikkei MC Aluminum America, Inc. is a U.S.-based secondary aluminum producer located in Columbus, Indiana. NMAA specializes in creating dependable aluminum alloy solutions for manufacturers across a wide range of demanding applications. With decades of experience, growing production capabilities, and the backing of a broader global network, we help customers source aluminum alloys built around performance, consistency, and quality.
History of Nikkei
Nikkei MC Aluminum America is part of a larger aluminum manufacturing network with roots in Japan. The business began as M.C. Aluminum Co., Ltd., with plants in Togura and Asaba before expanding to Tochigi as demand for secondary aluminum continued to grow.
In 1989, M.C. Aluminum America, Inc. was established in Columbus, Indiana through a joint venture between Mitsubishi Corporation, M.C. Aluminum Co., Ltd., Mitsubishi International Corporation, Enkei Corporation, and Enkei America, Inc. The company was originally created to recycle scrap generated by Enkei America’s wheel production facility and convert it into secondary aluminum.
Production in Columbus began in 1990 with one 20-metric-ton reverberatory furnace, one casting line, and a team of about 20 employees. Over time, the operation expanded steadily with additional furnaces, more casting capacity, and a growing workforce. Today, Nikkei MC Aluminum America operates with approximately 100 employees, three furnaces, four casting lines, and two chip dryers, producing more than 40,000 metric tons each year.
As the company grew, so did the broader Nikkei MC Aluminum network. Today, that network includes operations in Japan, Thailand, China, India, Mexico, and the United States, giving the Columbus facility the strength of a larger international manufacturing organization while maintaining its focus on serving customers in North America.
What We Do
Our product lineup includes alloys developed for high toughness, high wear resistance, high thermal conductivity, and high rigidity, along with other standard and custom alloy options tailored to customer needs. These materials are used in the production of a wide range of cast components, including shift forks, transmission components, compressor components, torque rods, piston components, and engine brackets.
Today, our Columbus operation produces both aluminum alloy ingots and molten aluminum for demanding manufacturing applications. Backed by disciplined production processes, recycled-material expertise, and the broader Nikkei MC Aluminum network, we help customers source reliable aluminum alloys for critical automotive and industrial uses.
