Stamping in Phosphor bronze C510 (spring temper)
Phosphor bronze C510 (spring temper) is a proven choice for stamping: good fatigue strength for cycled contacts and springs. On a representative bracket at 25,000 pieces it estimates at about $3.86 per part plus $32,890 tooling, with a lead time of 6–10 weeks. Typical tolerance is ±0.002–0.005 in (±0.05–0.13 mm) on pierced features; ±0.010 in (±0.25 mm) across bends.

C510 vs other stamping materials
The same bracket at 25,000 pieces, priced in every material the process runs. 1008 CRS is the lowest all-in cost.
| Material | Per part | All-in | Weight | Tensile |
|---|---|---|---|---|
| Steel 1008 cold-rolled (CRS) | $0.33 | $1.66 | 108 g | 330 MPa |
| Steel A36 (structural) | $0.34 | $1.68 | 108 g | 450 MPa |
| Aluminum 5052-H32 | $0.46 | $1.80 | 37 g | 228 MPa |
| Stainless steel 430 | $0.73 | $2.06 | 107 g | 483 MPa |
| Stainless steel 304 | $1.22 | $2.55 | 110 g | 505 MPa |

Strengths
- Good fatigue strength for cycled contacts and springs
- Non-magnetic, for sensor and instrument springs
- Resists corrosion and stress corrosion better than brass
- Solders and plates easily with tin, nickel, silver or gold
Watch for
- Conductivity of about 15% IACS; use C110 or a high-conductivity alloy for current-carrying parts
- Costs more than brass and much more than steel
- Spring temper limits bend radius; bend across the rolling direction or use a softer temper
- Relaxes faster than beryllium copper when hot; use BeCu for hot or high-stress contacts

Questions
How much does stamping in C510 cost?
For a representative part (l-bracket 50 mm × 70 mm legs, 60 mm wide, 2 mm thick, r2 mm bend, 4 × ø5.5 mm holes), SSG's estimator gives about $3.86 per part at 25,000 pieces, plus about $32,890 one-time tooling. All-in with tooling and setup that is $5.19 per part. It is budgetary; principals quote firm prices from your drawing.
Is C510 a good material for stamping?
It is when you need good fatigue strength for cycled contacts and springs and non-magnetic, for sensor and instrument springs. Watch for conductivity of about 15% iacs; use c110 or a high-conductivity alloy for current-carrying parts. Of 8 materials run in stamping, it ranks 8 on all-in cost for the same part.
What finishes work on C510 stamping parts?
Common options are vibratory deburr (tumbling), electroless nickel (en), heat treating. The builder adds each finish's lot charge, per-part cost and days to the estimate.
What tolerance can stamping hold in C510?
Typical capability is ±0.002–0.005 in (±0.05–0.13 mm) on pierced features; ±0.010 in (±0.25 mm) across bends. Tighter tolerances are possible on called-out features at added cost; specify them on the drawing rather than as a blanket note.
