C10200 Copper Busbar

Henan Gnee New Material Co., Ltd. is one of the most professional manufacturers and suppliers of c10200 copper busbar in China, specialized in providing high quality copper products with competitive price. Welcome to buy discount c10200 copper busbar for sale here from our factory. Customized orders are welcome.

C10200 (OF – Oxygen-Free) is a high-purity copper grade with 99.95% minimum copper content and maximum oxygen content of 0.001% (10 ppm). It is manufactured under controlled atmosphere to prevent oxygen absorption during melting and casting – but without the extra refining steps required for C10100.

C11000 contains 200-400 ppm oxygen. C10100 contains ≤5 ppm oxygen. C10200 sits in the middle with ≤10 ppm oxygen. For applications that require oxygen-free copper but do not need the ultimate purity of C10100, C10200 is the cost-effective choice.

C10200 vs C11000 vs C10100 – C10200 offers the same 100% IACS conductivity as both grades. The difference is oxygen content and price. If your application requires oxygen-free copper but cannot justify the C10100 premium, C10200 is the answer.

Chemical Composition of C10200 (ASTM B187)

Physical Properties of C10200

For standard electrical performance (ampacity, heat dissipation, mechanical strength), C10200, C11000, and C10100 are identical. The choice comes down to oxygen sensitivity and budget.

The current carrying capacity of C10200 copper busbar is the same as C11000 and C10100 – all have 100% IACS conductivity. The table below shows ampacity for bare flat busbars at 35°C ambient, 65°C max operating temperature.

Ampacity of C10200 Flat Copper Busbar

Unlike C12200 which has 85-95% IACS due to phosphorus, C10200 maintains full 100% IACS conductivity. You do not need to upsize your busbar when switching from C11000 to C10200.

No oxygen sensitivity → C11000

Oxygen sensitivity + tight budget → C10200

Oxygen sensitivity + extreme requirements → C10100

Price Comparison (Relative to C11000)

Cost example (50mm x 6mm x 2000mm busbar, 500 pieces)：

If your application requires oxygen-free copper, C10200 saves you 10-20% compared to C10100 with no practical difference for most applications. Unless you need the absolute lowest oxygen content (≤5 ppm), C10200 is the better value.

Grade selection support

What is different from C11000：

C10200 is slightly softer in annealed temper

No special considerations for welding (C10200 welds well)

Same tooling works – no additional cost

Tin plating and heat shrink for C10200 copper – if you plan to weld or braze the busbar, order bare. Plating must be removed before welding. We recommend：weld first, then plate the assembled part.

Q1：What is the MOQ for C10200 copper busbar?

For standard sizes (from our die library)： MOQ = 10 pieces per size.

For custom sizes (special width, thickness, or length not in standard list)： MOQ = 50 pieces per size.

For sample orders (any size, any shape)： No MOQ. We support small-batch prototype orders before mass production.

Standard sizes include：20mm, 25mm, 30mm, 40mm, 50mm, 60mm, 80mm, 100mm width with 3mm, 5mm, 6mm, 10mm thickness.

Q2：Do you provide samples of C10200 busbar?

Yes. Standard size samples：Free, customer pays shipping. Custom size samples：50 USD, refundable upon production order of 500+ pieces.

Sample lead time：5-7 business days for standard sizes, 7-10 days for custom sizes. Each sample includes a mill test certificate showing purity and oxygen content.

Q3：What is the lead time for C10200 orders?

Sample orders： 5-10 business days depending on complexity.

Production orders (standard sizes, no plating)： 10-15 business days.

Production orders (with tin/silver plating)： 15-20 business days.

Production orders (custom fabrication with bending)： 15-20 business days.

C10200 is a standard production item but less commonly stocked than C11000. For non-stock sizes, add 5-7 days.

Q4：C10200 vs C11000 – what's the difference?

Verdict： If your application does not require oxygen-free copper, use C11000. If oxygen-free is required, C10200 is the cost-effective choice.

Q5：C10200 vs C10100 – what's the difference?

Verdict： For most oxygen-free applications (hydrogen brazing, moderate vacuum, general oxygen sensitivity), C10200 is sufficient and saves 10-20% compared to C10100. Only choose C10100 for extreme requirements.

Q6：Is C10200 cheaper than C10100?

Yes. C10200 typically costs 10-20% less than C10100 while still providing oxygen-free performance (≤10 ppm vs ≤5 ppm). For most applications, the difference in oxygen content is not noticeable.

Q7：Do you provide tin plating for C10200?

Yes. Tin plating, silver plating, and heat shrink tubing are all available for C10200 busbars. However, if you plan to weld or braze the busbar, order bare – plating will contaminate the weld.

Q8：Is C10200 suitable for vacuum or cryogenic applications?

For moderate vacuum (10⁻³ to 10⁻⁵ torr)： Yes, C10200 works well. Its low outgassing (≤10 ppm oxygen) is sufficient for most vacuum applications.

For high vacuum (below 10⁻⁵ torr)： No, use C10100. High vacuum requires the absolute lowest oxygen content (≤5 ppm).

For cryogenic down to -150°C： Yes, C10200 maintains ductility. For cryogenic down to 4K (-269°C), use C10100 for best results.
