High-Purity T2 Copper Strip/Sheet | Precision Laser Cutting & Slitting Supported

Publish Time: 2026-03-14 13:34:56

T2 copper is all about ultra-high purity — its copper content reaches ≥99.90%, with impurities strictly controlled to minimal levels: Pb ≤ 0.005%, Bi ≤ 0.001%, Sb ≤ 0.002%, making it almost pure copper.

This high purity translates to tangible benefits: electrical conductivity of over 98%, and thermal conductivity second only to silver — more than 1.5 times that of regular brass. For those in the electrical and electronics industry, superior conductivity means lower current loss and faster heat dissipation, which is a game-changer for high-performance components.

Thickness Range	Core Features	Typical Applications	Processing Recommendations
0.05-0.3mm	Ultra-thin, flexible, excellent conductivity, highly formable	Precision electronic electrodes, instrument gaskets, shielding cases, battery connectors	Laser cutting for intricate patterns; slitting width customizable down to 5mm with zero deformation
0.3-1.0mm	Balanced flexibility & strength, easy to weld	Relay terminals, switch contacts, decorative nameplates, small heat sinks	Laser cutting for complex shapes; smooth cuts require no secondary polishing
1.0-5.0mm	High strength, stable conductivity, good wear resistance	Power distribution cabinet busbars, large heat sink bases, welding electrodes, copper art decorations	Direct laser cutting after slitting; ideal for mass production with ±0.1mm precision
5.0-20.0mm	Heavy-duty, excellent electrical & thermal conductivity	Industrial transformer copper strips, busbars, large mechanical conductive components	Laser cutting for large-size sheets; compatible with drilling and bending processes

The biggest headache when buying copper materials is usually processing hassle — burrs on cut edges, or deformation of thin strips. We solve this completely with our one-stop laser cutting + slitting service.

The advantages of laser cutting for T2 copper are clear:

Heat is concentrated in an extremely small area, resulting in a negligible heat-affected zone. Even 0.05mm ultra-thin strips stay flat with no edge warping after cutting.
Burr-free, smooth cuts with a surface roughness of ≤ Ra12.5, ready for direct use in subsequent production — saving you time and polishing costs.

Our slitting service is highly flexible:

Custom widths tailored to your exact needs, with precision controlled within ±0.1mm.
Perfect for both narrow strips (for electrodes) and wide strips (for busbars), minimizing material waste and reducing your production costs.

Application Scenarios of T2 Copper Strip/Sheet

Electronics & Electrical Industry: Relays, switch contacts, battery connectors, transformer coils — leveraging high conductivity to minimize current loss and ensure stable equipment operation.
Heat Dissipation & Refrigeration Industry: CPU heat sinks, refrigerator copper tubes, industrial radiators — thanks to exceptional thermal conductivity.
Decoration Industry: Copper relief carvings, antique door and window fittings, gift box packaging — delivering a warm, lustrous finish after polishing.
Welding Industry: Welding electrodes and brazing materials — with high temperature resistance and stable conductivity to guarantee consistent welding quality.

FAQ

Q: Which has better conductivity, T2 copper strip or brass strip?

A: T2 copper is the clear winner! With a copper content of ≥99.90%, its conductivity is over 98%, while brass (a copper-zinc alloy) only has about half that conductivity. Choose T2 copper for conductive or heat-dissipating components; opt for brass if strength and corrosion resistance are your top priorities.

Q: Will a thin oxide layer form on T2 copper strip after laser cutting? How to handle it?

A: A thin oxide film is normal after laser cutting. If surface appearance is not a strict requirement, the material can be used directly. For a bright, polished finish, we offer pickling or polishing services to remove the oxide layer and restore T2 copper’s natural reddish luster.

Q: Will 0.05mm ultra-thin T2 copper strip break during slitting?

A: Rest assured, it won’t! We use high-precision slitting equipment with precisely controlled tension. The slitting process won’t cause stretching or breakage, and the narrow strips produced have smooth, burr-free edges.

Q: Is T2 copper strip/sheet suitable for use in humid environments?

A: It’s fine for short-term use, but surface treatment is recommended for long-term exposure. T2 copper is prone to oxidation and tarnishing in humid conditions; plating, painting, or waxing can effectively prevent corrosion and extend its service life.

Q: What is the minimum slitting width? How long does mass customization take?

A: The minimum slitting width is 5mm, with a precision of ±0.1mm. In-stock standard sizes can be shipped the same day; mass customization orders have a lead time of 3–5 days, and rush orders can be prioritized for faster delivery.
