It is an improved variety that European countries introduced in the 1980s to replace tantalum tungsten products. Once introduced, it has attracted much attention and popularity in the international welding industry due to its excellent welding performance, especially sought after by the European Welding Academy. The export volume of tantalum tungsten electrode is second only to tantalum tungsten, but the recognition in the domestic market is not high. Its characteristic is that the conductive performance is closest to 2% é’ tungsten electrode, and the durable current is high and the burning rate is the smallest.
85% Semi-encrypted Silica Fume
85% Semi-encrypted Silica Fume, is a byproduct of the production of silicon and ferrosilicon alloys. It is a highly reactive pozzolan with a high silica content of over 85% and a bulk density of around 300 kg/m3. The specific surface area of 85% Densified Silica Fume is very high, ranging from 15,000 to 30,000 m2/kg, making it an ideal supplementary cementitious material for enhancing the strength, durability, and workability of concrete.
