Your Questions About Copper, Zinc, and Bronze Castings
Can Yongzhu Casting manufacture copper parts with tight tolerances?
Yes. Our copper casting processes can achieve dimensional tolerances of up to ±0.01 mm after CNC finishing, making them suitable for electrical connectors, terminals, and pump bodies.
What’s the difference between bronze and brass castings?
Bronze is typically stronger and more corrosion-resistant due to its tin content, while brass is more malleable and often used for decorative parts. Yongzhu specializes in bronze castings for industrial use.
What casting methods do you use for zinc alloy parts?
We use high-pressure die casting and low-pressure casting for zinc components, depending on the complexity and wall thickness required.
What’s the typical lead time for non-aluminum cast parts?
For small-batch orders, we typically ship within 15–20 working days. For larger quantities, lead time may range from 25–35 days depending on tooling and machining needs.
Do you support small-quantity or prototype orders for zinc or bronze?
Yes. We accept low-volume and prototyping orders starting from just 10 pieces. We also provide mold design and material recommendations during the development phase.
Can I request surface treatments for copper or bronze parts?
Absolutely. We offer nickel plating, chrome plating, polishing, sandblasting, and passivation services depending on the material and your end-use application.
How heavy can your castings be?
Our equipment supports single-part weights of up to 50 kg for gravity and sand casted non-aluminum parts, with consistent mechanical performance and structural integrity.
Which industries use your zinc and copper castings?
Our non-aluminum cast parts are widely used in lighting systems, medical housings, smart energy modules, plumbing fixtures, and custom hardware in home furnishings.
What kind of quality control do you apply to non-aluminum parts?
All non-aluminum parts go through the same rigorous QC process as aluminum ones: raw material testing, dimensional inspections (CMM), pressure testing (if required), and full visual checks.
How do I get a quote for copper, zinc, or bronze castings?
Simply contact us with your drawings, material choice, and quantity estimate. Our engineers will get back to you within 24 hours with a technical response and quotation.
