Frequently Asked Questions
What is JIS H 3300 C4430 Admiralty Brass Pipe?
JIS H 3300 C4430 is a copper-zinc-tin alloy pipe designed for good corrosion resistance and reliable heat-transfer performance.
What is JIS H 3300 C4430 used for?
It is used for condenser tubes, heat exchangers, evaporators, marine cooling systems, and other heat-transfer equipment.
Is C4430 Admiralty Brass suitable for seawater?
Yes. C4430 offers good resistance to seawater corrosion and is suitable for marine and seawater cooling systems.
What is the difference between C4430 and C6870 Aluminium Brass?
C4430 Admiralty Brass contains tin and is widely used for condenser tubes, while C6870 contains aluminum and arsenic and provides higher resistance to erosion-corrosion in high-velocity seawater.
Is C4430 suitable for condenser tubes?
Yes. C4430 is commonly used for condenser tubes because of its good corrosion resistance, thermal conductivity, and heat-transfer performance.
Can JIS H 3300 C4430 be used in heat exchangers?
Yes. C4430 is suitable for heat exchangers where good thermal conductivity and resistance to water-side corrosion are required.
