What's the material and finish for the black spring metal in this picture?
I am designing a spring and I want it to be flex and hard as this metal?
How should I specify in my drawing?

I was prompted by a vendor, but I am not sure if this is True.
He said that material is Manganese - Steel.
Does anybody here have any idea what material could this clip be made of?
And also, could it be pre heatreated or Post heat treated in real production?
Thanks

It will be then hardened and tempered, and finished as required.

1. Use spring steel (any specific ?)
2. Anneal before forming
3. Harden and temper after forming ( what temp / hrc ?)
Can anybody provide more info.
Thanks

RE: Material suggestion needed
Here is an example of a proper specification for this type of part:
Material: ASTM A684, 1050-1074 spheroidized annealed
Treatment: Austemper to 44-51 HRC
Coating: black electrocoat, thickness 10 μm minimum
Another option for the coating is black oxide. This can specified according to ISO 11408, DIN 50938, SAE AMS 2485, or MIL-DTL-13924.

In fact the answer from TVP (above) gave me all the information I needed. But was curious about AL you mentioned.
But I agree, It might be an alloy, if its AL.
