FAQs of NFA 51 102 CuZn30 70-30 Lead Free Brass:
Q: How is NFA 51 102 CuZn30 70-30 Lead Free Brass manufactured?
A: NFA 51 102 CuZn30 brass is produced by combining copper (approximately 70%) and zinc (approximately 30%) in a controlled environment, ensuring the lead content remains below 0.03%. The alloy is cast and processed into rods, then treated to achieve a half hard temper and a bright, polished surface finish.
Q: What are the primary applications of this lead free brass rod?
A: This alloy is widely used in industrial, electrical, and engineering sectors for products such as electrical connectors, fittings, precision components, and machinery parts, especially where both corrosion resistance and compliance with lead-free regulations are necessary.
Q: When should you choose lead free brass over traditional brass alloys?
A: Lead free brass is preferred for applications subject to strict environmental regulations and where lead contamination can pose health or safety risks, such as electrical systems, potable water components, and export-oriented products.
Q: Where is NFA 51 102 CuZn30 70-30 Lead Free Brass typically supplied from?
A: This lead free brass alloy rod is manufactured, exported, and supplied from India, meeting global standards and catering to customers in diverse international markets.
Q: What benefits does NFA 51 102 CuZn30 brass offer over other brass grades?
A: It combines excellent corrosion resistance, good machinability, bright appearance, and compliance with lead-free requirements, making it a favored material for precision engineering and safe electrical applications.
Q: How does the tolerance specification H9 / h9 impact its engineering uses?
A: The H9 / h9 tolerance ensures dimensional accuracy and consistency, which is crucial for manufacturing processes where parts are assembled with tight fits and precision is paramount.
