WHY BEDRA

Why bedra for series-ready automotive wire solutions?

bedra combines material expertise, process stability and application-focused support for automotive body manufacturing and automotive E/E production.

BODY JOINING & STRUCTURAL WELDING

Wire solutions for visible laser-brazed seams, aluminium battery frames and load-bearing structural joints

Wire solutions for visible laser-brazed seams, aluminium battery frames and load-bearing structural joints in automotive body manufacturing. What matters in production: tight tolerances, clean wire surfaces, stable feeding behaviour and reduced contamination.

BIW laser brazing for visible seams

Laser brazing on galvanised panels, e.g. roof seams and other visible joints in body-in-white structures.

Typical solution:

bercoweld^® S3 (CuSi3Mn1) for BIW laser brazing

Tight tolerances and low contamination help stabilise the laser brazing process
Supports paintable seam appearance in visible body areas

Aluminium welding for battery trays & module frames

Aluminium MIG/TIG welding for battery trays, underbody frames, battery module frames and profile joints.

Typical solution:

berAlweld^® 4047 (AlSi12) for battery trays and module frames

Reduced hot-crack sensitivity and strong fillet-weld performance
High flowability supports robust bead formation at corners and profile joints

Structural aluminium joints, nodes & subframes

Load-bearing structural joints, nodes, subframes and frame assemblies in aluminium body structures.

Typical solution:

berAlweld^® 5356 (AlMg5Cr(A)) for structural aluminium joints

Established filler for structural aluminium joints in series production
Stable feeding and repeatable weld quality support TCO

Applications & bedra solutions

Applications: BIW laser brazing (visible seams), battery trays and battery module frames, structural aluminium joints, nodes and subframes.

Core solutions: bercoweld^® S3, berAlweld^® 4047 and berAlweld^® 5356

Additional aluminium fillers on request: berAlweld^® 4043, berAlweld^® 5087 and berAlweld^® 5183.

Documentation & approvals: EN ISO / AWS references and selected TÜV documentation are available on request.

AUTOMOTIVE E/E MANUFACTURING

Wire as functional material for winding, heating and contact-element manufacturing

Wire as functional material for winding, heating and contact-element manufacturing in automotive E/E applications. What matters in production: defined insulation or enamel build, dimensional control where required, stable pay-off/feeding and clean surfaces.

CHALLENGES & RESPONSE

Material challenges in automotive wire processing — and the bedra response

Automotive components are becoming smaller, more complex and more functionally integrated. This increases the demands placed on wire materials, surfaces, geometries and automated production processes.

YOUR CHALLENGES

Miniaturization and package space
Lightweighting
EMI/EMC integrity
Thermal cycling
Corrosion and media resistance
Tolerances and process capability
Traceability
Stable automated processing

OUR RESPONSE

Materials expertise

In-house foundry and extensive competence across tin bronzes, brasses, nickel silver and specialty alloys engineered for defined electrical and mechanical properties.

Geometry breadth

Square, rectangular, octagonal, flat and round wire — smooth, knurled, coated or uncoated — each designed to customer-specific parameters.

Process precision

Ultra-tight dimensional tolerances, precise knurling, optimal straightness and stable pay-off behaviour help support stable processing in demanding applications.

Surface finishing

Pure tin, nickel/copper barrier layers, multilayer technology and reflow tinning support consistent surface quality and modern manufacturing requirements.
