- Some BEVEL undercutting at the edges of all dimensions will occur. This BEVEL is approximately 20% of material thickness when etching the sheet from 2 sides.
- Hole size generally cannot be less than material thickness.
- Outside radius corners are sharper than inside corners.
- Inside radius corners are usually limited to one half the material thickness.
MATERIALS COMMONLY USED:
- Aluminum, Beryllium Copper, Brass, Copper alloys Nickel Silver, Phosphorous Bronze, Stainless Steel, Steel.
- Material thicknesses usually within a range of .0005" to .060"
