I thought it was a very bad idea to use anything but the correct shear pin as the use of a material that has a much higher shear strength will defeat the purpose of the shear pin and allow the forces from a prop strike to damage engine internals.

When I was young and dumb I used sections I’d cut off from a brass rod my buddy gave me.  they worked a bit, but were too soft and didn’t last long.  Finding out exactly what the metalurgy is on those shear pins and getting a length of rod would be the way to go.
