Electric contacts for automobiles, electric contacts for home appliances, power contacts
Advanced specifications and cost competitiveness achieved through our unique material structure control technology
Mitsubishi Materials Trading supplies a variety of electrical contacts, many of which are made from silver-based materials. Our main products are automotive relays that operate power windows and wipers delivered to Tier 1 suppliers. Based on the technologies we have cultivated in the highly competitive automotive components industry, we also provide a range of consumer relays operating home appliances.
- Challenges faced by customers
- Customers demand that our electrical contacts achieve advanced specifications that are up to the needs created by the evolution of the products in which the electrical contacts will be installed. In particular, automotive electrical contacts demand high performance, following the evolution of the automobile itself, including developments such as the emergence of hybrid and electric vehicles.
Moreover, amid today's intensifying competition in the automotive components industry, the reduction of cost while improving performance is an ongoing challenge.
Solutions
With our customers' needs as a starting point, Mitsubishi Materials Trading always considers challenges from every perspective to provide solutions to our customers.
New Materials Proposals
Leveraging our unique processing technology to control material structures, we propose the development of materials and material properties that are best suited to our customers' needs. By customizing materials and their properties, we can improve their specifications, such as the improvement of welding and wear resistance, and the achievement of low contact resistance. Excellent welding and wear resistance lengthen the service lives of contacts, while low contact resistance reduces the amount of heat generated.
New Manufacturing Methods Proposals
We review our existing products, including their manufacturing methods, to propose products in shapes that are optimized for our customers' needs. Shape customization enables smaller, more compact designs to achieve space saving and cost reduction at the same time. In particular, our technique for producing smaller-sized and reduce-silver contacts can reduce the use of silver. This is key in cost reduction, and has been praised by our customers.

Advantages and Benefits for Customers
Contributing to the advancement of the customer's technologies
The production of automotive electrical contacts with advanced specifications starts with the development of new materials that meet the needs of the customers. This task involves the incorporation of an array of original, innovative efforts focused on multiple points in the process, including design and manufacturing methods. These tasks require continuing experimentation, often evaluating choices between two or more conflicting factors, as enhancing one particular performance field may sacrifice another.
Throughout the entire process, which may take several years, we value communication with our customers, and seek out and propose optimal solutions in close cooperation with our manufacturing contractors. We believe that our proposals for materials, shapes, and manufacturing methods will contribute to the development of electrical contacts, and also to the advancement of our customers' technologies.
Our environmental friendliness adds value
We deliver a wide range of products with advanced specifications, while extending the technologies and expertise cultivated through the intensifying quality and cost competition surrounding electrical contacts for automotive components and household appliances.
We also have a lineup of cadmium-free contacts for applications in automobiles and household appliances. As sustainability has become a global issue, we believe the value we add through our environmental friendliness will become even more important in the future.
A message from our representative
"Developing electrical contacts is a long-term project that requires persistent effort. Therefore, building trust with customers is vital, and we dedicate ourselves to these projects, keeping our ability to respond to customers in good faith our top priority.
Into the era of IoT, too, we expect the role of contact products to expand drastically. As this happens, contacts will relay data, not electricity. Although this will be technically more difficult, we will happily fulfill the roles that the times demand, while making our strengths in the bridging needs and technology available to our customers."
