Copper is a conglomerate composed of copper and lime. The varying chemical elemental content leads to differences between different types of copper. There are numerous international standards for designating metals and conglomerates. Here, we will discuss two types of copper from the GB/T system: H59 and H62. They share many similarities; what are the differences between them, and which to choose if it's H59 vs. H62 copper?
What are H59 Brass and H62 Brass?
Copper can be divided into plumbing copper and iron.
Copper is often confused with zinc. Copper is also often confused with copper and ink. White copper is often confused with copper and nickel. Copper H62 and H59 are both types of copper confusions, containing nearly 62% and 59% copper, respectively.
Copper H62 refers to a type of ordinary copper with an average copper content of 62%, where H62 is the first character of the Pinyin in Chinese characters and represents the average copper content. Ordinary copper, with added elements, is called special copper, which is also indicated by its additional chemical symbol and average proportion. For example, HAl59-3-2 contains 57-60% copper, 2.5%-3.5% aluminum, 2%-3% nickel, and the remainder is zinc.
H59 copper has high strength, high tensile strength, and low plasticity. Its corrosion resistance is average, and other properties are similar to H62.
H59 vs H62 Copper: Which to Choose? - The Differences Between H59 and H62
H62 and H59 are two common types of copper solder that are similar in appearance but differ in price. H62 is slightly more expensive due to its higher copper content. What are the other differences between H62 and H59, and which solderer should you choose for different applications?
1. The most important difference is the copper content and chemical composition.
Components of H59 copper:
Copper (Cu): 57 ~ 60%
Metals (Pb): ≤ 0.5%
Phosphorus (P): ≤ 0.01%
Iron (Fe): ≤ 0.3%
Stibium (Sb): ≤ 0.01%
Bismooth (Bi): ≤ 0.003%
Zinc (Zn): Remaining
Dirtiness: ≤ 1.0%
Components of H62 copper:
Copper (Cu): 60.5 ~ 63.5%
Iron (Fe): ≤ 0.15%
Metal (Pb): ≤ 0.08%
Stibium (Sb): ≤ 0.005%
Bismooth (Bi): ≤ 0.002%
Phosphorus (P): ≤ 0.01%
Zinc (Zn): Remaining
Dirtiness: ≤ 0.5%
2 features
H59 Features:
Tensile strength σb (MPa): ≥ 294
Length δ10 (%) ≥ 25
Operating temperature (hot): 730-820 °C
Metabolic temperature: 600 ~ 670 °C
H62 Features:
Tensile strength σb (MPa): ≥ 315
Length δ10 (%) ≥ 30
Operating temperature (hot): 650 ~ 850 °C
Metabolic temperature: 600 ~ 670 °C
Performance and Applications
H59 copper is inexpensive and has general corrosion resistance, so it is commonly used for machine parts, components, hot stamping and hot rolling parts. It is suitable for electrical equipment, electronics, electrical machinery, horizontal mounting, switches, sockets, battery contact parts, copper buttons, watch straps, necklaces, cuffs, rings and other copper products.
H62 copper possesses good mechanical properties, good corrosion resistance, and superior plasticity in both hot and cold conditions. It is easy to machine, copper, and insert, but it is also prone to corrosion cracking. It can be used for parts requiring high load resistance and is a good material for networking. Typical applications of H62 copper include coins, insect screens, washers, ventilation equipment, the sugar industry, shipbuilding, the paper industry, and other parts.
