Bronze vs steel alloy as it relates to thickness and oscillation rate.
I'm working on a Schumer disc pend. clock. I've been servicing this clock for the past ten years now and recently the lady brought the clock in and during transport if fell over and broke the sus. spring, The original spring is blued steel .0035 thick and 1.5mm wide. I replaced it with 1mm wide alloy steel of the same thickness and it ran seriously slow. I change it out with .004 thickness spring material and still it's running very slow. I'm sure the issue is the width of the spring material and haven't found anything wider than 1mm The only thicker spring material I've found is bronze.
