What are the effects of alloying elements on aluminum bronze
The effects of alloying elements on aluminum bronze are as follows: Iron Fe: 1. Excessive iron in the alloy will precipitate needle-like FeAl3 compounds in the tissue, resulting in changes in mechanical properties and deterioration of corrosion resistance; 2. Iron slows down the diffusion of atom...Read more -
Smelting of oxygen free copper
Strictly distinguish, oxygen free copper should be divided into ordinary and high purity anaerobic copper. Ordinary oxygen free copper can be smelted in a power frequency core induction furnace, while high purity oxygen-free copper should be smelted in a vacuum induction furnace. When semi contin...Read more -
Notes on oxygen free copper casting
Oxygen free copper refers to pure copper that does not contain oxygen or any deoxidizer residue. In the production and production of anaerobic copper rod, processed anaerobic copper is used as the raw material for production and casting. The quality of oxygen free copper rod made of good quality ...Read more -
Performance advantages of chrome zirconium copper electrodes
The excellent thermal conductivity of chrome zirconium copper electrode is about 3~4 times better than that of die steel. This feature ensures rapid and uniform cooling of plastic products, reduces deformation of products, unclear shape details and similar defects, and significantly shorens the p...Read more -
Key points of aluminum bronze semi – continuous casting process
Aluminum bronze has the casting properties of strong suction, easy oxidation slag, large solidification shrinkage, poor thermal conductivity, and poor casting performance. Before casting, tin bronze manufacturers used a mixture of some alkali earth metal compounds, such as Na₃AlF₆ and NaF, as a s...Read more -
