Hardness: 36-43 Rockwell C
Density: .298 lbs/in3
Electrical Conductivity: 22% IACS*
Resistance: 10 mΩ Max
Operating Temperature: -55°C/+125°C
Melting point: 980°C/865°C (liquidus/solidus)
Stress Relaxation : 96% of stress remains after 1,000 hours @ 100 °C; 70% of stress remains after 1,000 hours @ 200 °C
*International Annealed Copper Standard, i.e. as a % of pure copper.
Since BeCu loses its spring properties over time at high temperatures; it is rated for continuous use up to 150°C. For applications up to
300°C, Mill-Max offers other materials. Contact Tech Support for more info.

LOOSE PIN/RECEPTACLE USED:
1304 (Brass Alloy)
BRASS ALLOY 360 per ASTM B 16, or 385 per ASTM B455
Properties of BRASS ALLOY 360 ASTM B 16:
Chemical composition: Cu 63% (max), Pb 3.7% (max)†, Fe .35% (max), Zn remainder
Temper as machined: H02/H04
Yield Strength: 25-45 ksi
Tensile strength: 57-80 ksi
Hardness as machined: 80-90 Rockwell B
Electrical conductivity: 26% IACS*
Melting point: 1000°C/840°C (liquidus/solidus)
Properties of BRASS ALLOY 385 ASTM B 455:
Chemical composition: Cu 60% (max), Pb 3.5% (max)†, Fe .35% (max), Zn remainder
Temper as machined: H02/H04
Yield Strength: 16 ksi(min)
Tensile strength: 48 ksi(min)
Hardness as machined: 80-90 Rockwell B
Electrical conductivity: 28% IACS*
Melting point: 1000°C/840°C (liquidus/solidus)
After machining, brass parts are often annealed (softened) for subsequent bending, swaging or crimping. A partial anneal down to 60±10 RB
is recommended for 90° bends, a full anneal down to 35±15 RB is recommended for pins or terminals that are swaged (riveted) to a circuit
board or crimped to a wire.
Note: Plated Brass parts need a barrier plate to prevent zinc diffusion, 50μ” min. nickel or 100μ” min. copper is recommended by ASTM B
545 and 579. ASTM B 488 also recommends a 50μ” min. nickel barrier plate beneath gold to prevent copper diffusion inherent with all
copper alloy products.
†RoHS-2 directive 2011/65/EU, exemption 6c allows up to 4% lead as an alloy agent in copper.

INSULATOR MATERIAL:
PCT Polyester (Injection Molded)
Properties:
Product Number 803-43-008-10-001000 Data Sheet mill-max.com Updated 12/27/20 8:59 PM EST - Page 2 of 3
Polyester {30% glass filled}, High Temp., (black). Flammability rating UL 94 V-O
Rated voltage: 100 VRMS/150 VDC
Insulation resistance: 10,000 Megaohms min.
Material Heat Deflection Temp (per ASTM D 648): 529°F (276°C) @ 66 psi
Dielectric strength: 1000 VRMS min. (700 VRMS min. for series 117 Shrink DIP)
Note: Materials with HDT above 446°F (230°C) are considered suitable for “eutectic” reflow soldering. For
“lead-free” reflow soldering, choose materials with an HDT above 500°F (260°C). PCT is the standard plastic
used with RoHS “lead-free” plated pins.

ADDITIONAL NOTES & SPECIFICATIONS
In the interest of improved design, quality and performance , Mill-Max reserves the right to make changes in its specifications without prior
notice. Specifications and tolerances are provided wherever possible. The tolerance on dimensions of critical to function features is typically
held tighter than the stated standard tolerances, such as press-fits, holes and lengths affecting the coplanarity of SMT products. Due to the
wide variety of interconnects Mill-Max offers, the specific tolerances vary from product to product. If you need information regarding the
tolerance of a particular part, please contact Technical Services.
