大橋鉄工 List of Products and Services

"Friction welding technology" is a technique that utilizes the thermal energy generated by friction and strong pressure, enabling the joining of dissimilar metals and non-ferrous metals that are very difficult to join using conventional welding techniques. While durable materials tend to be expensive, it is possible to use durable materials only where necessary and cheaper materials elsewhere, allowing for the provision of joining materials that balance durability and cost. Our company has a proven track record in applications such as electronic components like copy rollers and motor shafts, as well as mechanical parts. [Features] - Balancing durability and cost - Combination of different properties - Provision of "titanium-heat-resistant steel" joining materials that balance corrosion resistance and heat resistance - Proven applications in electronic components and mechanical parts *For more details, please refer to the PDF document or feel free to contact us.
