... relatively low levels. Once again, two versions of one of the AS-series alloys, AS41, are available. The main difference between AS41A and AS41B is that higher copper levels are allowed in AS41A than in AS41B. Therefore, AS41B has better saltwater corrosion resistance than AS41A. Beryllium is added to...
