FAQ
Q1: How to choose between H62, H65, H68, and H70 brass grades?
A: To put it simply:
Choose H62 if you need high strength and cost-effectiveness — ideal for structural components.
Choose H65 or H68 for deep drawing, stretching, and complex hardware parts — they resist cracking during forming.
Choose H70 for high-end electronic components requiring both strength and excellent conductivity.
Q2: What is the minimum and maximum thickness available? How precise is the laser cutting?
A: Our regular in-stock thickness ranges from 0.05mm to 2.0mm. Within this range, laser cutting achieves high precision (typically ±0.05mm or better, depending on your design drawings), with smooth, burr-free edges perfect for precision machining.
Q3: Is there a minimum width limit for slitting processing?
A: For stable slitting results, we generally recommend a minimum width of 5mm. Narrower widths may lead to edge curling issues.
Q4: Can you provide material certification?
A: Absolutely! Material certificates (including SGS reports) are provided with each shipment, ensuring compliance with national standards and hassle-free factory inspections.
Q5: Is the price negotiable for large-volume orders?
A: Definitely! We adopt a volume-based pricing strategy — the larger the order quantity, the more favorable the price. Whether for laser cutting or slitting services, we offer our best factory-direct prices for bulk orders. Feel free to contact us for a detailed quote!
