Materials for universal use
Category B
Main characteristics: 

high strength properties: 70–110 MPa (yieldstress, tensile strength, compressive strength),
toughness (notched Charpy): 12 kJ/m2 – does not break,
good sliding properties : m = 0,15–0,5 (dry sliding on smoothed and ground steel),
wide temperature range for application: from –40°C to +140°C,
high hardness (Rockwell): M 85 – M 98,
good fatigue strength and damping capability,
good wear resistance,
favorable creep resistance: 18 – 26 MPa, tension for 1% extension in 1000 h,
density: 1,15 – 1,16 kg/dm3

Basic grade: 
PA 6 cast, extruded PA 66 extruded PA 4.6 extruded PA 12 extruded
Special grade: 
Fiber reinforced and/or lubricant filled base materials are available to ensure special properties (better sliding, wear resistance, greater strength, dimensional stability).
Main areas of use: 
Bearing bushings, wear pads, sleeve bearing, guide and conveyor rollers, rope pulleys, cams, gear wheels, gear racks, hob gears, buffer blocks, chain gears, hammer heads, blades, strippers, insulating elements, gasket rings, insulators, etc. In the event of wet environment and/or precision components, the dimensional change arising from the water absorption of polyamides has to be taken into account, as well as the modified material characteristics when calculating load-carrying capacity!
Machining technology: 

Cutting (turning, milling, drilling, reaming, sawing): only traditional metalworking – or in certain cases, woodworking tools – carbon steel, rapid steel, hard metal, diamond can be used only in sharp design. Cooling is recommended, which allows high cutting rates, e. g. v = 100-500 m/min for turning and milling, v = 50 –100 m/min for drilling.
Adhesive bonding and welding: feasible.

Color: natural, blue

It offers a favorable combination of strength, toughness, mechanical damping ability and wear resistance. All this is accompanied by good electric insulating and chemically resistant properties. Based on all of the above, the product can be regarded as a polyamide type “for general use”.
