He is very much opposed to the use of binding wires, particularly steel, as he considers that due to the difference in the coefficient of expansion of the steel and solder there is a continuous rubbing action when heating up and cooling, resulting in the wires coming unstuck. He has obtained better results with phosphor bronze wires. BY/Btn. | ||
