H65 brass strip is a copper-zinc binary alloy with a copper content ranging from 63.5% to 68%, which is higher than that of the commonly used H62 brass. This optimal composition ratio delivers exceptional plasticity, ensuring the material resists cracking during bending, deep drawing, or complex forming processes. It also boasts a high surface finish, eliminating the need for additional polishing in subsequent processing. With strictly controlled impurity levels (Pb ≤ 0.03%, Fe ≤ 0.1%), it is safe for use in electronic components and food-contact products.
For 0.05-2.0mm H65 brass strip, we provide professional laser cutting and slitting services. Our high-power fiber laser cutting technology ensures fast processing speed, producing smooth, burr-free cuts that require no secondary finishing. As a non-contact processing method, it avoids material deformation — even for 0.05mm ultra-thin strips, the flatness is perfectly maintained. Our slitting service offers fully customizable widths, with neat, burr-free edges and a straightness tolerance of ≤ 3mm per meter.

FAQ
Q: How to choose between H65 and H62 brass strip?
A: H65 has a higher copper content (63.5%-68%), offering superior plasticity and deep drawing performance, making it perfect for products requiring complex forming and high surface quality. H62 has a copper content of 60.5%-63.5%, with slightly higher strength but average plasticity, suitable for general hardware parts. Choose H62 for budget-friendly options, and H65 for enhanced machinability.
Q: Will 0.05mm ultra-thin H65 brass strip warp during laser cutting?
A: No. We use fiber laser cutting, a non-contact process that exerts no mechanical stress on the material. Nitrogen assist gas is also applied to prevent oxidation during cutting. Even for 0.05mm ultra-thin strips, flatness is maintained and cuts are burr-free.
Q: What is the range of customizable slitting widths? Is there a minimum width limit?
A: Slitting widths are fully customizable with no fixed restrictions, ranging from a few millimeters to standard wide formats. Our high-precision slitting equipment ensures smooth, curl-free edges, with thickness tolerance controlled within ±0.01mm.
Q: Do you support customization and after-sales service for small-batch purchases?
A: Yes! We accept both small-batch orders and custom-specification requests. Standard sizes can be shipped on the same day, while custom sizes have a lead time of 7-15 days. Our after-sales service includes technical consultation, quality issue resolution, and provision of material inspection reports.
