Abstract

Steel material has resistance to rust and strong magnetic properties, as well as resistance to loads. Aluminum is of high strength and corrosion resistance. Most of the technical equipment is under rotary dynamic load pressure. The component that receives the most dynamic load is the shaft. The shaft receiving the shipment can be a fixed load, a shock load, or a combination of the two packs. Shaft fatigue failure will be more visible when experiencing shock loads. This shock load can occur during the initial movement, braking, gear shifting, or external shock load. Fatigue results in fractures that look brittle and without deformation in the fracture. The manufacture of the shaft requires a mechanical test, including stress, strain, and hardness factor. This study, comparing the mechanical properties between ST 145 steel and aluminum alloy (Al-Si), in which the two materials have high strength. The purpose of this study was to determine whether the ST 145 steel and aluminum alloy meet the requirements as a shaft material in terms of mechanical aspects. The test material sample is in the form of a specimen using ASTM standards—research by testing steel and aluminum material with a diameter of 6 mm. Mechanical testing resulted in the maximum stress of steel 85,124 kg / mm2, and aluminum 19.05 kg / mm2; the ultimate steel strain was 8.03% and aluminum 7.796%. The hardening factor of steel was 0.771, and aluminum was 0.243.
