Frequently asked questions

Can I buy brass and copper fittings direct from the manufacturer?

Yes — Brassland is a manufacturer in Jamnagar, India, not a distributor, so you order machined brass and copper parts direct to your drawing, with factory pricing, full material traceability and ISO 9001 quality. Request a quote.

What does the Brassland blog cover?

Technical, engineering-focused guides across brass and copper alloys, dezincification and corrosion, thread standards (BSP/NPT/JIC), CNC and Swiss machining, compliance (RoHS, REACH, WRAS, NSF 61) and sourcing from India.

Are the blog's technical claims referenced?

Yes — articles cite recognised standards bodies (ISO, ASTM, EN/BSI, NSF, WRAS, ECHA) and link to Brassland's own standards and material references, each with a last-reviewed date.

How do I choose the right alloy or fitting for my application?

Start with the alloy guide and material datasheets, then the relevant application or standards article; for a specific part, send a drawing and our engineers advise on grade, tolerance and compliance.
