AMS 4534 ultimate tensile and Rockwell hardness properties in a peak aged condition are in the 200 ksi range and RC 45 respectively (electrical conductivity 22% IACS minimum). Most commonly utilized beryllium copper and is notable for exhibiting the highest strength and hardness compared to commercial copper alloys. Its strength and hardness is similar to that of steel.

5 REASONS AEROSPACE CHOOSES AMS 4534
Weight-to-Strength Champion
“Replaces steel springs at 65% weight savings—every gram counts when launching satellites at $10.000/kg.”
Conductivity Meets Durability
“Carries 10X more current than stainless steel while surviving 100M+ cycles in F-35 landing gear.”
Non-Sparking & Non-Magnetic
"Essential for fuel tank sensors and munitions plants—passes explosive atmosphere certifications (ATEX/EN 13463).”
Corrosion Warrior
“Resists salt fog, hydraulic fluids, and UV degradation. Zero failures in 30-year submarine connectors.”
Precision-Perfect Machinability
“Machines like brass pre-hardening; heat-treats to micron tolerances. Ideal for laser-cut EMI shields.”
PROCESS: HOW WE MET THE RIGOR OF AMS 4534
1 Vacuum Induction Melting
“Beryllium (1.8-2.0%) fused in oxygen-free chambers (<20 ppm impurities). Safer than open-air casting.”
2 Precision Hot Rolling
“Formed under 800°C to ±0.005mm tolerance—critical for wafer-thin RF shields.”
3 Solution Annealing
“Rapid-quenched at 790°C to lock beryllium atoms in suspension.”
4 Age Hardening Alchemy
“320°C for 3 hours: beryllium precipitates form nano-scale armor, boosting strength 3X.”
APPLICATIONS: WHERE TRUST IS NON-NEGOTIABLE
| Industry | Critical Use Cases | Why AMS 4534? |
