LEONI DRAHT GMBH

High-flexible copper-based ropes, enclosed by an additional braid, made from Cu-ETP1, Cu-OF1 and LEONI Histral® alloys (upon request) in bare, tin-plated, nickel-plated and silver-plated, hard or soft annealed. Single-wire diameter ranging from Ø 0.05 mm to Ø 0.10 mm. Cross-section ranging from 0.35 mm² to 120 mm² (bigger cross-sections upon request). Our ropes with overall braids are characterised by their good flexibility and their excellent mechanical strength. The overall braid has a vibration-reducing function and prevents unrevelling of the rope. Ropes with overall braids are mainly suitable for automotive, industrial applications and for connectors.

Compacted material terminals made from Cu-ETP1 and Cu-OF1, in bare and tin-plated, nickel-plated and silver-plated upon request, in hard or soft annealed. Cross-section ranging from 1 mm² to 95 mm² depending on welding area. Compact welded terminals of different copper strands can be automated processed. A production of individual parts is possible as well as large-scale production. Resistance welded strands by LEONI are particularly suitable for high-voltage battery connectors, for high power connectors, for switch contacts and for special applications.

Compact braided square and rectangular copper flexibles made from Cu-ETP1, Cu-OF1 and LEONI Histral® alloys (upon request) in bare, tin-plated or silver-plated. Single-wire diameter ranging from Ø 0.05 mm to Ø 0.20 mm. Cross-section ranging from 0.47 mm² to 50 mm² (further dimensions upon request). Square copper braids require less space in comparison to round copper braids with the same cross-section. There is a precise positioning owing to square or rectangular shape, which allows for failure-free and fully automated downstream manufacture. Squre or rectangular copper braids are characterised by very good Flex life, being absolute free from twist, a compact cutting surface, a very high degree of dimensional accuracy and a very long lifetime. Compact braided square and rectangular copper flexibles are particularly suitable for applications in carbon brushes industry, connection technology, switches and aviation industry.

Compact braided round copper flexibles made from Cu-ETP1 and Cu-OF1, LEONI Histral® alloys upon request, in bare, tin-plated, nickel-plated or silver-plated, in hard or soft annealed. Single-wire diameter ranging from Ø 0.05 mm to Ø 0.10 mm. Cross-section ranging from 0.047 mm² to 25 mm² (bigger cross-sections upon request). Round copper braids are characterised by a very high degree of dimensional accuracy and a very high Flex life. They are absolute free from twist and support an automatic further processing. Compact braided round copper flexibles are particularly suitable for carbon brushes industry, connection technology, switches or aviation industry.

Round copper wire made from Cu-ETP1, Cu-OF1 and LEONI Histral® alloys, in bare, tin-plated, nickel-plated and silver-plated, soft annealed. Single wire diameter ranging from Ø 0.05 mm to Ø 0.254 mm. Number of wires used for strands: between 2 and 16 (subject to single-wire diameter). Single wire or multi wire on special bobbins fit for use in braiding machines. The braids manufactured by these machines are used in cables and conductors geared towards electromagnetic shielding or protection against damage as well as serving as a reinforcement.

Several bunched single wires or bundles made from Cu-ETP1 and Cu-OF1 in bare, tin-plated, nickel-plated or silver-plated, soft annealed. Single-wire diameter ranging from Ø 0.05 mm to Ø 0.51 mm, left-hand lay or right-hand lay. Cross-section ranging from 0.005 mm² to 630 mm². Those single wires do not hold a fixed position inside the strand. Their position relative to one another undergoes a permanent change along the entire length of the bunch. The construction of a bunch is derived from the cross-section required, which leads to the electrical conductor featuring a certain resistance level. Different cross-sections with the same resistance value can be generated by applying single wires of varying sizes. Owing to their good efficiency our bunched single wires are versatile in a multitude of applications in cables and conductors.

Semi-concentric or concentric strands with very short lay lengths and an extraordinarily smooth surface made from Cu-ETP1 and Cu-OF1 in bare, tin-plated, nickel-plated or silver-plated, soft annealed. Single-wire diameter ranging from Ø 0.05 mm to Ø 0.51 mm, left-hand lay or right-hand lay. Cross-section ranging from 0.02 mm² to 16 mm². LEONI has had its manufacturing process specifically dedicated to this type of product patented. LEONI smooth bunches boast an exceptionally compact and precise round structure and have a very good Flex life. They are particularly suitable for moving applications and for thin-gauge coating with high-grade isolation materials benefitting from a long flex life as well as weight and space efficiency.

Strands with a semi-concentric structure made from Cu-ETP1, Cu-OF1 and LEONI Histral® alloys in bare, tin-plated, nickel-plated or silver-plated, soft annealed. Single-wire diameter ranging from Ø 0.05 mm to Ø 0.51 mm, left-hand lay or right-hand lay. Cross-section ranging from 0.03 mm² to 16 mm². The individual wires are subject to an exact positioning, yet without an additional core wire, which ensures an all-out uniform structure. Concentric strands are particularly appropriate for thin-gauge coating with high-grade isolation materials (extrusions). The technical qualities of a semi-concentric strand can be extremely well and accurately customized by combining several different alloy wires.

Strands with a concentric structure made from Cu-ETP1, Cu-OF1 and LEONI Histral® alloys in bare, tin-plated, nickel-plated or silver-plated, soft annealed. Single-wire diameter ranging from Ø 0.05 mm to Ø 0.51 mm, left-hand lay or right-hand lay. Cross-section ranging from 0.02 mm² to 630 mm². The individual wires are subject to an exact positioning around a core wire, which ensures an all-out uniform structure. Concentric strands are particularly appropriate for thin-gauge coating with high-grade isolation materials (extrusions). 7-end strands are especially suited for data cables with high frequencies of transmission. The technical qualities of a concentric strand can be extremely well and accurately customized by combining several different alloy wires.

Round copper wires made from Cu-ETP1 and Cu-OF1 in bare, tin-plated, nickel-plated, silver-plated or gold-plated, soft annealed. Single-wire diameter ranging from Ø 0.05 mm to Ø 0.51 mm. Number of wires used for strands: between 3 and 24 wires (subject to single-wire diameter).
