ហេតុអ្វីបានជាសមាសធាតុបរិក្ខារដ៏សំខាន់ធ្វើពីលង្ហិន?

 

In the bathroom industry, ច្រើនជាង 85% of mid-to-high-end faucets choose H59-H62 brass as the main material instead of stainless steel or zinc alloy. This choice is not accidental, 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.

 

1. Physical properties: irreplaceable engineering advantages

1)Casting liquidity

លង្ហិន (copper content 59%-62%) has excellent fluidity in liquid state and can perfectly fill the fine structure of complex molds. Comparative experiments show:

លង្ហិន: can cast 0.2mm fine lines (such as antique relief)

asys zinc: the minimum is only 0.8mm, and it is easy to produce bubbles

ដែកអ៊ីណុក: 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 ដែកអ៊ីណុក: 120 seconds/piece (tool wear rate increased by 3 ដង)

 

 

2. 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. ផ្ទុយទៅវិញ, 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. asys zinc, ម៉្យាងទៀត, 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.

 

 

3. Cost-effectiveness: economic efficiency throughout the entire life cycle

Although the current high price of brass makes the price of faucets prohibitive, តាមពិត, the high yield rate is also one of the factors that affect the final result. នៅ​ពេល​បច្ចុប្បន្ន, the unit price of H59 brass is 52,000 RMB, and the yield rate is 98%, while the price of stainless steel and ZAMAK is 16,000 RMB and 24,000 RMB, but the yield rate is only 89% និង 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

 

1. 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)

 

ការបហ្ចប់: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 ឆ្នាំ. 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.
