About DLB Draht und Litzen GmbH
DLB Draht und Litzen GmbH is a manufacturer of high-quality wires, stranded wires, strands and ropes made of copper and copper alloys, with headquarters and production site in Berlin. Manufacturing includes wire drawing in heavy-drawing and medium-drawing with induction annealing, multi-wire drawing, electroplated wire tinning, roll compaction (Einbügeln), as well as stranding and bunching on machines of types 630 to 1250. The product range extends from single wires through bunch strands, concentric strands (Unilay, True Concentric) and semi-concentric strands to ropes and strands made of copper alloys for high tensile loads. Customers are national and international companies from the automotive industry, domestic appliance engineering, energy generation and photovoltaics, mechanical engineering, and telecommunications, marine and railway technology. As part of the medium-sized corporate group comprising BEHG Holding AG, KBE Elektrotechnik GmbH and DLB Oberviechtach GmbH & Co. KG, the company manufactures with tight production tolerances and has been developing customer-specific quality products for 25 years. For applications and offers: offers exclusively to business customers.

Materials and processes
Copper
Base material for wires, strands and ropes with tight tolerance fields for diameter and resistance.
Copper alloys
Used for strands with higher requirements, especially in medium drawing with induction annealing.
Tin (tinning)
Electroplated surface coating for tinning of the wire with uniform layer thicknesses.
