We supply these tricky custom 17-7PH springs to our aerospace customer - unlike the other compression and extension 17-7PH springs we supply the same customer, these are C shaped with two .165" length oval openings. The material thickness was set to .020" and the outside diameter at .550-.555". The angle between the ends was the more challenging part, set at 130 +/-5 degrees. The oval openings incorporated a full radius on both sides and the width was limited to .062" max. A FAIR and material certs were provided with the parts.
