H68 Brass Strip | 67-70% Copper Content | Burr-Free Laser Cutting & Custom Slitting

Publish Time: 2026-03-14 11:55:01

H68 brass strip is no ordinary brass alloy — it boasts a high copper content of 67-70%, with zinc as the balance element and strictly controlled impurities (Pb ≤ 0.03%, Fe ≤ 0.10%). This optimized composition makes it the most ductile grade among brass alloys. As professionals in industrial parts and decorative product manufacturing know, superior ductility means the material resists cracking during bending, stretching, and deep drawing processes. It handles complex applications like intricate electronic component housings and jewelry prototypes with ease. Additionally, it offers good electrical and thermal conductivity, along with better corrosion resistance than regular carbon steel, ensuring long service life without rusting in daily environments.

Tired of cumbersome processing for brass strips? We offer one-stop integrated processing services, combining laser cutting and slitting in a single workflow. Laser cutting comes with a host of benefits: the cuts are smooth and burr-free, with a positioning accuracy of 0.05mm. Intricate patterns and tiny holes can be cut with pinpoint precision, eliminating the need for secondary finishing. Our slitting service is highly flexible — widths can be customized to your exact requirements, minimizing material waste and reducing production costs. What’s more, the non-contact cutting process prevents surface scratches, ensuring both the appearance and performance of the final product meet the highest standards.

FAQ

Q: What’s the difference between H68 brass strip and regular brass?

A: The core difference lies in composition and performance! H68 has a copper content of 67-70%, delivering far superior ductility and formability compared to regular brass grades. It is ideal for products requiring complex shaping and high surface quality, while regular brass is more suitable for simple components with lower performance requirements.

Q: Does H68 brass strip need secondary polishing after laser cutting?

A: Basically no! Laser-cut edges are smooth and flat, free of burrs and edge collapse. The parts can be directly used in subsequent production processes, saving both time and polishing costs.

Q: Will 0.05mm ultra-thin H68 brass strip warp during laser cutting?

A: Rest assured, it won’t! Laser cutting concentrates heat in a tiny area, resulting in an extremely narrow heat-affected zone. This allows for distortion-free cutting even on ultra-thin brass strips, preserving their excellent flexibility after processing.

Q: Can H68 brass strip be used in humid environments like coastal areas?

A: Yes, but surface treatment (such as plating or painting) is recommended! H68 resists general corrosion, but it is prone to corrosion in salt-laden humid air. Surface treatment will significantly extend its service life. For long-term immersion in seawater, we recommend H68A (arsenic-added grade), which offers enhanced corrosion resistance.

Q: How precise is the slitting width? What’s the minimum width available?

A: Slitting precision can be controlled within ±0.1mm, with a minimum width of 5mm. Whether you need narrow strips for electrodes or wide strips for housings, we can meet your exact needs with consistent quality, even in mass production.
