How Much Does B30 Copper-nickel Pipe Cost Per Kilogram?

B30 copper-nickel alloy is a high-performance copper-based alloy. Due to its excellent corrosion resistance, high strength and good processing performance, it is widely used in petrochemical, marine engineering, pharmaceutical and other fields. This article will deeply analyze the performance and market situation of B30 copper-nickel alloy pipe from the aspects of technical parameters, industry standards, material selection misunderstandings, etc., and explore its price influencing factors.

1. Technical parameters of B30 copper-nickel alloy pipe

The chemical composition of B30 copper-nickel alloy is mainly composed of copper (Cu) and nickel (Ni), usually containing about 75% copper and 20% nickel, and the rest are trace alloying elements. This composition makes it perform well in moderately corrosive environments, especially in environments containing chloride ions.

According to the ASTMB929 standard, the typical performance parameters of B30 alloy are as follows:

Tensile strength: ≥515MPa

Yield strength: ≥275MPa

Elongation: ≥30%

Corrosion resistance: Excellent in seawater, brine and industrial solutions

Conductivity: The conductivity is about 70%IACS (International Annealed Copper Standard)

According to the AMS4965 standard, B30 alloy has good hot working properties and is suitable for cold and hot working and welding.

2. Industry standards and international market

In the international market, the price of B30 copper-nickel alloy is affected by many factors, including raw material price fluctuations, market demand changes, and production costs. Here are some key points:

Raw material prices: The price fluctuations of copper and nickel have a direct impact on the production cost of B30 alloy. For example, the copper price of the London Metal Exchange (LME) and the nickel price of Shanghai Nonferrous Network are important references for the global market.

Market supply and demand: Investment fluctuations in the petrochemical industry directly affect the demand for B30 alloy. In recent years, with the recovery of the global energy industry, the demand for B30 alloy has increased.

International trade: Due to the high production concentration of B30 alloy, the international price difference is large. For example, the price difference between the US market and the Chinese market may reach 5-10%.

3. Material selection misunderstandings

When choosing B30 copper-nickel alloy, you need to pay attention to the following three common misunderstandings:

Confusing alloy grades: B30 and copper-nickel alloys such as B10 have significant differences in composition and performance. When selecting materials, the alloy grade must be clarified to avoid substandard performance due to confusion.

Ignoring the use environment: B30 alloy may not be as suitable as other alloys (such as bronze or stainless steel) in certain specific environments. Environmental conditions must be considered comprehensively when selecting materials.

Simply pursuing low prices: The price of B30 alloy is relatively high, but its performance advantages may bring higher economic benefits in long-term use. Cost and performance must be balanced when selecting materials.

4. Technical controversy: Performance comparison between B30 and B10 alloys

In material selection, the performance comparison between B30 and B10 alloys is a hot topic. The following are the key comparisons between the two alloys:

Composition and performance: B30 alloy has a higher nickel content, so it is superior to B10 alloy in corrosion resistance and strength. However, B10 alloy has better processing performance and lower cost.

Application scenarios: B30 alloy is suitable for highly corrosive environments, while B10 alloy is more suitable for general corrosive environments and light load occasions.

5. Price analysis and market trends

According to data from Shanghai Nonferrous Network, the price of B30 copper-nickel alloy pipes in 2023 is about RMB120-150 yuan/kg, and the specific price depends on the pipe specifications, surface treatment and market supply and demand. The fluctuation of LME copper prices has a particularly significant impact on the price of B30 alloy. Generally, for every 10% increase in copper prices, the price of B30 alloy will increase by 5-8%.

6. Summary

The price of B30 copper-nickel alloy pipes is affected by many factors. Technical parameters, industry standards and use environment should be considered comprehensively when selecting materials. Avoiding material selection errors and clarifying the alloy properties can maximize its advantages in practical applications.
