Clad & Weld Process

Our proprietary Clad & Weld process creates metallurgically bonded bimetallic materials with superior performance characteristics.

Key Process Characteristics

Solid-State Bonding

  • • No melting of base metals during the bonding process
  • • Preserves the original properties of both metals
  • • Creates a true metallurgical bond at the interface

High Bond Strength

  • • Bond strength ≥ 60 MPa
  • • Significantly higher than electroplated alternatives
  • • Consistent interface quality across the entire length

Material Combinations

Copper Clad Aluminum (CCA)

Copper cladding ratio: 60%-90%

Lightweight, excellent conductivity

Copper Clad Steel (CCS)

Copper cladding ratio: 10%-40%

High strength for demanding applications

Nickel Clad Copper (NCC)

Various nickel ratios available

Corrosion resistance for harsh environments

Silver Clad Copper (SCC)

High-conductivity applications

Premium performance for precision applications

Process Declaration

All our bimetallic products are manufactured using the Clad & Weld process with metallurgical bonding, NOT electroplated. This ensures superior bond strength, durability, and performance.

Bond Strength ≥ 60 MPa

Process Visualization

Clad & Weld Process Diagram
Schematic Diagram
01. Cleaning

Removes oxides and impurities from raw material surfaces to ensure atomic-level contact.

02. Bonding

Physically presses two metals together under high pressure to form an initial mechanical bond.

03. Diffusion

High-temperature annealing causes atoms to diffuse across the interface, forming a metallurgical bond.

Key Technical Parameters

Parameter Range Note
Diffusion Temp 800°C - 1000°C Depends on material combo
Bonding Pressure > 100 MPa Ensures gap-free contact
Thickness Tolerance ± 0.005 mm High precision control

FAQ

How does Clad & Weld differ from Electroplating?
Electroplating is a chemical deposition process with weak bonding (physical adhesion only). Clad & Weld achieves atomic diffusion through high heat and pressure, creating a metallurgical bond that is strong and will not peel.
Does this process affect conductivity?
No. Since the interface is bonded at the atomic level, electrons pass through smoothly with no significant contact resistance. In fact, due to fewer impurities, high-frequency performance is often superior to electroplated products.
