Class 3 Copper
Class 3 Alloy is specifically recommended for projection welding
dies, flash and butt welding dies, current carrying shafts and
bushings. As castings,
Class 3 Alloy (having higher strength
than Class2), is recommended for highly stressed welder structural
current carrying members and heavy duty offset electrode holders.
Class 3 Alloy is generally recommended for spot welding and seam
welding steels having high electrical resistance, such as stainless
steels.
The Class 3 Alloy is heat treatable.

Class 4 Copper
Class 4 Alloy has extremely high hardness and ultimate
tensile strength although the electrical conductivity is lower than
the Class 3 Alloy
Class 4 Beryllium Copper (17200) is available in heat
treatable tempers. Alloys are used in a wide range of applications
requiring high strength and stiffness with good conductivity.
Typical uses include electrical/electronic connectors,
current-carrying springs, precision screw machined parts, welding
electrodes, bearings, plastic molds and corrosion resistant
components.

TB00 or A
This produces the softest form of the material. This
is the condition or temper resulting from heating the material to a
temperature sufficient to allow the beryllium to dissolve into a
solid solution within the copper base metal, followed by rapid
cooling.
Hardness (17510): B20-45
TF00 or AT
This process is often referred to as Aging, Age Hardening or Heat
Treating. This is the condition or temper resulting from the
application of a specific time and temperature combination.
This action produces an extreme strengthening effect within the
material. The tensile properties change from copper-like to
steel-like and the thermal and electrical properties also increase.
The specific combination of time and temperature applied determines
the final properties.
Hardness (17510): B92-100
TD04 or H
In Beryllium Copper this means that the material is
processed like the TB00/A temper material and then gets drawn
through a die to make a shape. The extra drawing through the
die makes the material harder.
Hardness (17510): B78-88
TH04 or HT
In Beryllium Copper this means that the material is
carefully annealed and then cold drawn to a specific size and then
heat treated.
Hardness (17510): B95-102
