01 / MATERIAL OVERVIEWMaterial Features

C11000 is electrolytic tough-pitch copper, widely used for electrical conductors. Low electrical resistance is valuable, while the complete busbar design also depends on dimensions, joints, support and operating conditions. For a separate fluid or heat-transfer circuit, explore C12200 straight copper tube or C12200 copper coil tube; these are tubing formats, not direct busbar substitutes.

Electrical Conductivity

Select conductivity requirements and test conditions in the purchase specification.

Contact Design

Joint area, surface condition and connection pressure affect contact performance.

Fabrication Options

Drilling, bending and tapping can be specified using a dimensioned drawing.

Surface Choices

Bare, tin-plated or nickel-plated options may be discussed for the intended connection.

Mechanical Support

Consider bar span, thermal movement and forces under the design operating conditions.

Material Identification

ETP is not oxygen-free copper. Confirm the grade when the process requires a different oxygen level.

02 / TECHNICAL DATAMaterial Reference

Item	Reference / requirement
Grade	UNS C11000
Copper including silver	99.90% minimum reference
Material type	Electrolytic tough-pitch copper
Electrical conductivity	Typically about 101% IACS at 20°C
Delivery properties	Specify temper and acceptance tests

Reference values support material selection. Confirm the complete chemistry, mechanical properties and acceptance criteria in the purchase specification and batch report.

03 / CONDITION & PERFORMANCESpecify the Right Condition

The grade does not define a universal hardness or current rating. Specify temper to match bending and support requirements. Conductivity figures are material reference values, not an ampacity rating for a complete assembly.

Requirement	What to confirm
Material condition	Exact grade and temper or delivery condition
Mechanical properties	Applicable limits for the product form and dimensions
Inspection	Test method and required material documentation

04 / DIMENSIONS & SUPPLYDimensions for Your Application

Item	Ordering guidance
Thickness × width	Specify section and tolerances
Length	Provide finished length and cutting requirements
Holes & bends	Supply a drawing with dimensions and datums
Contact surfaces	Specify flatness, finish and coating

Provide dimensions in millimeters and identify whether they refer to incoming stock or finished parts. Available sizes, quantity and lead time are confirmed in the quotation.

05 / APPLICATIONSTypical Applications

Switchgear

Conductors designed for the complete switchgear assembly.

Distribution Panels

Power connection bars with defined mounting and insulation clearances.

Bus Ducts

Straight sections and joints made to the approved layout.

Transformer Links

Connection bars with suitable flexibility, support and contact details.

Energy Equipment

Conductive components designed for the system current and temperature rise.

Grounding Systems

Ground and bonding bars selected to meet project requirements.

06 / FABRICATION & FINISHPlan the Fabrication Route

Operation	Details to define
Cutting & drilling	Specify dimensions, hole positions, burr limits and end finish.
Bending	Define inside radius and bend orientation, and match the temper to the forming operation.
Contact preparation	Specify flatness and surface finish on mating areas.
Plating	Define coating type, thickness, masked areas and final fit allowances.

07 / PACKING & INSPECTIONPacking, Handling & Inspection

Protect the Material

Specify package size and unit weight for your handling equipment. Agree on edge protection, separation between pieces and moisture protection appropriate to the shipment.

Store & Handle Carefully

Store dry and supported. Keep contact surfaces and finished faces free from contamination and handling damage. Preserve labels for batch identification.

Check on Receipt

Match grade, condition and batch identification to the order.
Check quantity, dimensions and packaging condition.
Inspect visible surfaces and edges before fabrication.
Review the agreed material and inspection documents.

08 / FREQUENTLY ASKED QUESTIONSSelection FAQs

What current can this busbar carry?

There is no single rating from the grade alone. The assembly design must consider section, temperature rise, cooling, enclosure and joints.

Is C11000 oxygen-free copper?

No. It is ETP copper. Specify an oxygen-free grade separately if required by the process.

Can the bar be plated?

Discuss tin or nickel plating with coating thickness and masking defined in the order.

09 / ORDERING GUIDESend a Complete Specification
