Material: Copper busbar, copper rod
Dimensional tolerance: within general tolerance range
We accept challenges for dimensional tolerance! Please contact us.
Lot:1 to 100 pieces (orders available from 1 piece)
Industries and applications:
Used in the electrical equipment industry for transformers, control panels, and distribution board components.
Material dimensions:Specializing in copper busbars from 3 mm to 20 mm.
Regularly processing copper rods with diameters from 10 mm to 55 mm.
Processing Machines and Methods: Press processing, machining, lathe processing
Features:JIS standard

Copper busbars comply with JIS H 3140.
Copper strips and plates (we refer to standard-sized plates like 365×1200 mm thickness) comply with JIS H 3100.
Copper rods comply with JIS H 3250 standards.

Our copper busbars are sourced through material trading companies from both domestic and international manufacturers, such as Mitsubishi Materials, Oriental Copper, and Furukawa Electric.

In order to be distributed as JIS-certified products, the following criteria must be met for copper busbar production:

Composition:
Oxygen-free copper (C1020) with a purity of 99.96% or higher
Tough pitch copper (C1100) with a purity of 99.90% or higher

Mechanical Properties:
Tests such as bending tests, conductivity tests, and hydrogen embrittlement tests are conducted by analyzing samples taken from ingots or finished products.

Length Tolerance:
Allowable length deviation is +15 mm, ±0 mm. Bending tolerance is also measured at this time.

Edge Shape:
The edges are rounded with a radius of 1.0 mm or chamfered with a flat surface of 1.0 mm or less. Burrs generated during manufacturing must not remain. The edges of the busbars from all manufacturers are rounded.
For each lot of copper busbars manufactured, a composition inspection is mandatory, and an inspection certificate, called a mill sheet, is kept by the manufacturer.

If a traceability certificate for the materials is required, please inform your sales representative when placing your order. We can request it during material procurement and deliver it together with the product, though it will be a copy. However, please note that it will not be included unless requested.

A major advantage of copper busbars is that a manufacturing process free from harmful substances has been established for about 70 years, making it easy to perform detailed inspections in case of any trouble or when receiving deliveries. This is why copper is considered a "miracle material" that can safely deliver electricity and heat.
