Photovoltaic welding ribbon<\/a>The cost of mining is closely related to the prices of nonferrous metals such as copper and tin.RAYTRON<\/a>For example, our company's main production costs include direct material costs, manufacturing costs, labor costs and transportation costs, among which direct material costs account for the highest proportion, accounting for more than 90%.<\/p>\n

Direct material costs are mainly copper purchases, accounting for 70.93%, tin alloy costs account for 28.91%, and flux costs are very low, accounting for 0.16%.<\/p>\n

Copper is an important component of the surface coating of photovoltaic welding ribbons and mainly plays a conductive role.<\/p>\n

The copper of different specifications in the substrate requires precise size, good conductivity and certain strength. The higher the purity of copper, the lower the resistivity, the greater the load-bearing capacity and the better the plasticity, so the copper substrate of photovoltaic welding ribbon is generally high-purity oxygen-free copper.<\/p>\n

The copper substrate of photovoltaic welding ribbons usually adopts secondary oxygen-free copper (divided by oxygen content and impurity content) with a purity of 99.95%, an oxygen content not exceeding 0.003%, and a total impurity content not exceeding 0.05%.<\/p>\n
