.webp "C27000 65/35 Lead Free Brass Pipe (CuZn35)")
C27000 65/35 lead free brass pipe is made from a yellow brass with a nominal 65 per cent copper and 35 per cent zinc, written CuZn35. The permitted copper range is wider, 63.0 to 68.5 per cent. No lead is added, and the lead limit is 0.10 per cent maximum. C27000 brass pipe and C27000 brass tube are used in electrical fittings, architectural hardware, plumbing parts and general engineering.
At Amardeep Steel Centre, we understand that selecting the right brass is about more than matching a grade number on a drawing. As a C27000 brass tube supplier in India, we help buyers identify suitable brass products for their requirements.

Applications of C27000 65/35 Lead Free Brass Pipe
C27000 is chosen where a part is formed, drawn or cold worked from tube and the water is not aggressive. It machines at a low rating, so free cutting brass is the better choice for turned parts.
- Plumbing and sanitary hardware: Fittings, connectors and water parts. Check potable water regulations before use.
- Electrical fittings: Suitable for terminals, connectors and components requiring brass’s electrical conductivity.
- Automotive components: Used in fittings and precision parts where formability and corrosion resistance are important.
- Building hardware: Applied in decorative fittings, handles and architectural components.
- General engineering: Used for machined parts, sleeves and tubular components.

Frequently Asked Questions
What is C27000 65/35 lead free brass pipe?
C27000 is a copper zinc brass alloy containing approximately 65% copper and 35% zinc, with controlled lead content. It is also known as CuZn35 brass.
Is C27000 really lead free?
C27000 is marketed as lead free brass, but its specification permits up to 0.10% lead. Check the material certificate and applicable regulations.
What does 65/35 mean?
The 65/35 designation refers to the approximate proportions of copper and zinc in the brass alloy: 65% copper and 35% zinc.
What is the difference between C27000 and C26000?
C27000 contains approximately 65% copper, while C26000 contains approximately 70% copper. Their zinc content and properties differ, affecting forming and application suitability.
Is C27000 suitable for drinking water pipe?
Not automatically. Confirm the alloy’s certification and compliance with applicable potable water regulations before using C27000 brass pipe in drinking water systems.
Is C27000 the same as CuZn35, CW507L and JIS C2700?
CuZn35 is a commonly used composition designation for C27000. CW507L and JIS C2700 may have differences, so verify standards and certificates before substitution.
