Shaped Charge Liner Material

Our Spinodal strip materials in Copper-Nickel-Tin alloys offer high ductility for forming into shaped charge liner material for the perforation of oil and gas well liners.

Shaped Charge Liner Material Advantages

The Spinodal material is produced through our wrought powder compaction process which imparts properties allowing the material to virtually ‘disappear’ upon activating the charge. The material is well suited to “big hole” applications for perforating charges and leaves little residue (commonly referred to as ‘carrots’ or ‘slugs’).

Pfinodal® (C72900) and AM-388™ (UNS C72650)

We produce two spinodal alloys for these shaped charge applications Pfinodal® (C72900) copper alloy and AM-388™ (UNS C72650). They benefit from age hardening techniques that further increase their strength and hardness required for deep hole penetration applications. These spinodal materials deliver superior mechanical and physical properties in comparison to conventional high-performance alloys for use in copper cone shaped charge applications for oil well perforating.

Hardenable Spinodal Strip via Wrought Powder Metallurgy

Pfinodal® c72900 copper alloy strip can be age hardened with a heat treatment to ensure the high hardness required for deep hole penetration applications. The heat treatment produces superior mechanical properties up to 195 ksi ultimate tensile strength (1344 MPa) and 410 Hardness (VHN). These properties make the materials highly suited for conical shaped charge applications for the perforation of oil and gas well liners. AM-388™ strip can be age hardened up to 155 ksi ultimate tensile strength (1068 MPa) and 380 Hardness (VHN). Alloys that are age hardenable, non-magnetic and non-conductive are best suited for the oil and gas industry. Both of these hardenable strip products can be roll-tempered to meet highly precise mechanical properties.

Tungsten and Copper Powders for Deep Hole Penetration

Additionally, AMETEK Specialty Metal Products carries both Tungsten and Copper powders and maintains the capability to blend these powders for customizing chemistries for deep hole penetration applications.
