在衛浴行業, 多於 85% 的中高端水龍頭選擇H59-H62黃銅作為主要材料，而不是不銹鋼或鋅合金. 這個選擇並非偶然, but the inevitable result of the comprehensive game of physical properties, chemical properties, and process costs. This article reveals the dominance of brass from four dimensions.
- Physical properties: irreplaceable engineering advantages
1)Casting liquidity
黃銅 (copper content 59%-62%) has excellent fluidity in liquid state and can perfectly fill the fine structure of complex molds. Comparative experiments show:
黃銅: can cast 0.2mm fine lines (such as antique relief)
鋅合金: the minimum is only 0.8mm, and it is easy to produce bubbles
不銹鋼: requires ultra-high temperature smelting (1500℃ vs brass 900℃), energy consumption increased by 40%
2)Machinability
The hardness of brass (HB80-110) allows it to be both precise and efficient when turning threads:
Processing time for brass valve bodies: 45 seconds/piece
304 不銹鋼: 120 seconds/piece (tool wear rate increased by 3 次)
- Chemical stability: a molecular barrier for long-term corrosion protection
One of the most significant advantages of brass is its exceptional corrosion resistance. Brass is an alloy mainly composed of copper and zinc, and copper’s natural anti – corrosive properties play a vital role. When exposed to moisture, which is inevitable in a plumbing environment, brass forms a protective patina on its surface. This patina acts as a barrier, preventing further oxidation and corrosion. 相比之下, although stainless steel is known for its corrosion resistance, in some specific water conditions with high levels of certain chemicals or minerals, it can still experience pitting corrosion. 鋅合金, 另一方面, is more prone to corrosion and degradation over time when in contact with water. Prolonged exposure to moisture can cause zinc alloy to weaken, leading to leaks and structural failures in faucet bodies.
- Cost-effectiveness: economic efficiency throughout the entire life cycle
Although the current high price of brass makes the price of faucets prohibitive, 實際上, the high yield rate is also one of the factors that affect the final result. 現在, the unit price of H59 brass is 52,000 人民幣, and the yield rate is 98%, while the price of stainless steel and ZAMAK is 16,000 RMB and 24,000 人民幣, but the yield rate is only 89% 和 93%.
Brass also has excellent ductility, which is very suitable for the complex shapes required for faucet manufacturing. Manufacturers can easily cast, forge and process brass into a variety of complex designs, from stylish modern styles to gorgeous traditional styles. This ductility enables it to create precise internal channels and threads in the faucet body, ensuring the tight fit of internal components such as valves and valve cores. Although stainless steel can be formed, it is more difficult to process due to its high strength and hardness. The processing technology of stainless steel requires more professional equipment and higher energy consumption, which increases production costs. Zinc alloy has better formability than stainless steel, but it is not as strong and durable as brass, and it is easy to deform under stress during the manufacturing process or in actual use.
4.Industry regulations: a hard requirement for global entry
- Lead control standards
Modern lead-free brass (such as CuSi1 alloy) solves the lead precipitation problem of traditional brass through three core technologies:
Lead washing process: surface lead content ≤0.25%
Grain boundary blocking: adding bismuth (Bi) elements to replace the cutting properties of lead
Certification guarantee: NSF/ANSI 61 certification (lead precipitation ≤5μg/L)
結論:The future of the brass dynasty
With breakthroughs in technologies such as CuFe2P alloy (strength increased by 40%) and nano-coating, brass will continue to dominate the bathroom sector for at least 20 年. For buyers, choosing a genuine H59 or higher brass faucet is essentially choosing a “10-year maintenance-free” engineering insurance – behind this is the ultimate answer to the century-long evolution of materials science.
