As a top international manufacturer of high-quality precision wires of non-ferrous metals, we distinguish ourselves in the market through high quality and smart services. Absolute customer focus. This is a long tradition for us - ever since the company was founded in 1889. Our ability to innovate, along with our well-known reliability, set us apart. These two strengths have made bedra a leader in quality and a leader in the market. Year after year, our plants produce more than 30 million kilometers of precision wire - in over 100 alloy versions. Our business units are: bedra EDM bedra WELDING bedraELAS We are known for customer-specific solutions across all service areas. Our highly qualified employees play a major role in this. We rely exclusively on high-quality metals for manufacturing our products. This makes our innovative high-tech precision wires absolutely alloy-pure. For more than 130 years bedra has been synonymous with innovative high-tech precision wires. From our plants in Heuchelheim and Herborn, we serve the needs of our customers all over the world. For decades, our bercoweld® series has established itself in the market for copper and copper alloy brazing and welding. More than 20 bercoweld® alloys are impressive proof of our know-how. But we are not resting on our laurels. We are already working today on the innovations for tomorrow. That's why we have expanded our portfolio to include high-quality filler materials made from aluminum alloys. Under the name be-rAlweld® we now offer wire solutions for welding aluminum alloys. For this purpose, we have combined our experience in wire production with the latest technologies and specialists from the aluminum sector. Therefore, we can now produce aluminum welding wires in the well-known high bedra quality! Whether you prefer MIG/MAG brazing or welding, TIG welding, laser and plasma brazing or wire flame spraying, our bercoweld® and berAlweld® range is as ‘diverse as your applications. This is one of the reasons why renowned companies from the automotive industry, plant engineering or the offshore and onshore sectors rely on our solder wire and welding wire as an elementary component of an innovative joining technology. At present, our range of solder wire and welding wire includes about 30 alloys of the following material groups • low alloyed Copper alloys • Aluminum bronzes • Copper-nickel' alloys • Aluminum alloys • Special alloys " ;■ Automotive Construction Railway track Industry Agricultural machinery Shipbuilding
