99.96% High-Purity C1020 Oxygen-Free Copper Strip | 0.02-6.0mm Full Range

When selecting copper materials, purity and size compatibility are make-or-break factors! Our C1020 copper strip/sheet is oxygen-free high-conductivity copper, with a guaranteed copper content of ≥99.96% and negligible impurities. It outperforms regular copper in durability and stability, while its thickness range of 0.02-6.0mm covers every application need — from 0.02mm ultra-thin electronic shrapnel to 6.0mm heavy-duty architectural panels and mold inserts. Boasting top-tier electrical and thermal conductivity in the pure copper category, it enables fast electricity transmission and stable heat dissipation, and resists cracking even in vacuum or high-temperature reducing environments.

The biggest headaches when purchasing copper are limited stock, long lead times, and processing hassles — we solve all of these! Our C1020 copper strip/sheet is in stock across the entire 0.02-6.0mm range. Whether you need 0.02mm ultra-thin strip or 6.0mm thick sheet, we ship the same day you order. We offer customizable processing services including cut-to-size, slitting, stamping, and bending. The minimum slitting width is 5mm with a cutting precision of ±0.05mm, and even ultra-thin strips maintain flatness post-cutting — ready for direct production use without secondary finishing.

A: Simply put, C1020 is oxygen-free copper (oxygen content ≤ 0.003%), with zero hydrogen embrittlement risk — ideal for welding and high-temperature processing scenarios. C1100 is regular pure copper (oxygen content ≤ 0.06%) with higher cost-effectiveness. Choose C1020 for precision electronics and welded components; C1100 works perfectly for general conductive and heat-dissipating parts.

A: While 0.02mm strip is extremely thin, we package it on rigid paper cores, wrapped with protective film and placed in hard cartons to prevent deformation during transit. We recommend storing it flat without stacking heavy objects after receipt, and using vacuum suction cups for feeding during processing.

A: Absolutely! Its high surface finish makes it perfect for nickel plating, tin plating, passivation, and other treatments. Passivation forms a protective film that enhances oxidation resistance and extends shelf life by 1-2 years. We also offer professional surface treatment services, delivering ready-to-use parts directly to you.

A: Yes! Orders of 50kg or more qualify for wholesale pricing; orders over 100kg get an extra 3% unit price discount. For long-term customers with quarterly purchases exceeding 500kg, an additional 2% rebate applies. We also provide free samples — check the quality before placing bulk orders, no strings attached!

A: Yes! With a melting point of 1083℃, C1020 maintains stable performance in long-term operating environments below 300℃ without oxidation or deformation. Note: Avoid using it in reducing atmospheres above 370℃, as this may cause intergranular cracking. It is fully compatible with normal industrial processing temperatures (e.g., annealing, welding).
