Product Detailed
Material: aluminum alloy 4032 or alminum alloy 2618 Bore:51-106mm Cylinder:4/8/16 Pin:steel alloy H13 high performance,racing

We are one of the professional manufaturers engaged in forged piston field.  We provide the most superior products in China, competed with JE, Wiseco and etc.

 

High performance forged piston Material: 4032 2618 4A11

Main Features: 1) alloy 4A11, 4032, 26182) anti-high temperature3) high performance index4) anti-friction

4032 forged piston blankPistons that are made from 4032 wrought aluminum alloy are designed for street/strip applications utilizing compression ratios that are compatible with pump gas. These pistons also provide a quieter engine on cold start-up. Physical Properties of 4032Nominal Density 2.68 g/CC. 097 lb/in3Mechanical Properties of 4032Tensile Strength, Ultimate 380 MPa 55, 000 psiTensile Strength, Yield 315 MPa 46, 000 psiModulus of Elasticity 79 GPa 11, 400 psiFatigue Endurance Limit 110 MPa 16, 000 psi

2618 forged piston blank Pistons made from 2618 wrought aluminum alloy are designed for higher performance applications such as FlyWeight or domed highcompression pistons. These environments necessitate the higher tensile strength 2618 aluminum alloy. Physical Properties of 2618Nominal Density 2.81 g/CC. 100 lb/in3Mechanical Properties of 2618Tensile Strength, Ultimate 440 MPa 64, 000 psiTensile Strength, Yield 370 MPa 54, 000 psiModulus of Elasticity 74 GPa 10, 400 psiFatigue Endurance Limit 125 MPa 18, 000 psi

Coefficient of Thermal Expansion2618 aluminum expands approximately 15% more than 4032 aluminum, thus the 2618's initial piston-to-wall clearance has to be 15% greater. This difference is most noticeable during a cold engine start. When cold, the 2618 piston can rock back and forth producing a slight noise (sometimes referred to as piston slap)Until the aluminum expands. Both types of aluminum have approximately the same clearances once the pistons have expanded and the engine is running at operating temperatures. Temperature Range Average CoefficientC F μm/m K μin/in F20 to 200 68 to 392 23.2 12.9

Coefficient of Thermal Expansion for 2618Temperature Range Average CoefficientC F μm/m K μin/inF20 to 200 68 to 392 20.2 11.2

EXAMPLE: When measured at room temperature, a 4 inch diameter piston made from 4032 measures 4.000". If the same piston weremeasured at 375, the piston would measure 4.0034".
