offering multiple benefits compared to production using billets. The process ensures homogeneous product specifications, reduces inclusions and allows delivery of larger lots on coil. Lamifil nv https://lamifil.be Lämneå Bruk AB 09 A06 After more than two years’ absence from international trade fairs, the Lämneå Bruk team is looking forward to interesting conversations at its stand.

manufacturer of cable and wire products, specialises in these new types of alloys. In terms of conductivity and resistivity, the new generation of copper alloy wires can almost compete with pure copper, but outperform it in areas such as flex life, elongation and tensile strength. CuCrZr and CuCrAgSi alloys can be drawn to extremely fine wires – down to 0.025mm – that remain strong and flexible. The modern production processes give these alloy wires good surface quality and purity, making them suitable for metal plating and less prone to corrosion. Aerospace is one industry where copper wires must meet the highest requirements. For sensitive electrical applications in aircraft parts such as wings, engines and sensors, high performance copper conductors in CuCrZr and CuCrAgSi are increasingly being used. Typically, these require high flex life (nine times higher than Cu-ETP), 92 per cent IACS conductivity, high tensile strength in soft condition (Rm = 414 MPa), 6 per cent elongation and high thermal stability. Currently 10 per cent of all copper cables in modern aircraft are high performance conductors. In the medical industry, copper and copper alloy wire is used in a variety of applications and devices, including catheterisation, sensor devices, surgery robotics and pace makers. Evolving technology and the need for smaller and mobile equipment are accelerating the search for alternative alloys to saveweight and space while remaining dependable, safe and precise.

10 G66 Krenn is a specialist in cutting and straightening wire and bars. The company’s electro-hydraulic straightener with rechargeable lithium-ion battery has been established for more than ten years. The design has been improved, making it tougher and more powerful. The battery-powered KTR-3 ACNL hydraulic straightener handles wires/bars up to 32mm maximum diameter, with a 380 bar operating pressure and 11-metric-ton pressure capacity.

Krenn’s battery-powered hydraulic straightener

While being easy to operate, it remains fast and flexible. Equipped with a sturdy rotatable straightening head and a rocker switch for easy forward/backward feed control, it is powered by an 18V Li-ion battery toensuremaximumflexibility. The KTR-3 ACNL is suitable for straightening wire when working off coils, as well as wire samples in the testing lab. Krenn GmbH & Co KG is a family-owned and managed business located in Bavaria, Germany. It has been operating in the wire processing industry for 70 years, and specialises in engineering, manufacturing and sales of manual, pneumatic and (electro-) hydraulic steel cutters and material testing presses for upset testing of wire samples. Its portfolio also includes straightening and bending machines, as well as customer-specific tailored solutions. Krenn GmbH & Co KG www.krenn.de 10 A47 As technology advances, many industries are looking for smaller, lighter high performance electrical components to meet demands in efficiency, reliability and conductivity. As a result, wires made from copper alloys such as CuCrZr and CuCrAgSi are increasingly finding their way into modern airplanes, advanced robots and medical devices. Lamifil, a Lamifil nv

No Twist Coiler 1200

Having been in the wire industry for more than 100 years, Lämneå Bruk has specialised knowledge as well as the ability to find innovative solutions for the changing demands of international customers. All machines are designed and manufactured on-site in Sweden, allowing for flexibility to adapt each machine according to the specific production requirements. Those looking for a machine that can streamline and modernise the entire wire production process will find at Lämneå Bruk’s stand one of the company’s newest innovations: the No Twist Coiler 1200. This machine acts as payoff and take-up for the drawing machine, for streamlined wire production. The main advantage is the handling of the wire package as undriven payoff, resulting in twist-free and straight wire. The machine saves energy and has less downtime due to its continuous production ability. Lämneå Bruk will run the machine live at its newly designed stand at wire Düsseldorf – daily at 9:45, 10:45, 13:45 and 15:45, except for Friday, when the last demonstration will be at 14:45. The team will advise visitors about how to get production ready for the future.

Lamifil is developing new copper alloys

Lamifil develops new copper alloys, including its CuCrZr PowerFil alloy, with applications in demanding and high-tech industries. The company has invested in order to develop stronger, finer, highly conductive and environmentally friendly alternatives. It offers in-house design, manufacturing, quality control and supply of wire rod, drawn and extruded wires, bunched and stranded conductors and surface-treated wires. Lamifil uses a unique continuous, automated and stable casting process for its high performance copper alloys,
