Can you deep draw ultra-hard or high-strength materials?

Reviewed by: pending engineering reviewStatus: draft6 cited sources

Answer

Material Selection: For deep drawing, you need materials with high anisotropy (r-value above 1.6) and elongation over 30%. Low yield-to-tensile strength ratios—below 0.65—give you the best formability and reduce cracking risk. : Deep drawing requires materials with high anisotropy (r-value above 1.6) and elongation above 30%. Materials with low yield-to-tensile strength ratios (below 0.65) perform best.

    High repeatability with low material waste Micro drawing can combine circular, rectangular, and custom features with repeatability that's hard to match with turning or milling. Since the shape comes from material flow, scrap and machining chips stay minimal. This process suits precision series produ...

What an engineer still needs from you

  • material and material condition (grade, temper)
  • material thickness, plus the key diameter, height and wall thickness
  • tolerances, burr direction and the visual acceptance standard
  • annual volume - it decides whether tooling is single-hit, progressive or transfer
  • surface finish, and any secondary machining, annealing or plating
Next step. Send the drawing for a manufacturability review, or send the part data for a process and cost route.
