Abstract

Aluminum and its alloys are the second largest metal material used after steel. Aluminum applications and alloys are very diverse, ranging from buildings, vehicle bodies, engine components, components to ships, to applications on aircraft. The strength and hardness of aluminum alloys are high, one application of aluminum as a component on a ship is as a material for making propellers on traditional fishing boats, more specifically aluminum alloy. Used aluminum can be obtained from the remnants of the industry making aluminum doors, windows and frames, making aluminum racks and storefronts, and other products with aluminum profile as the main material. many of them use aluminum alloy scrap as their main casting material to reduce their production costs. Evaporative or casting casting using Styrofoam or lost foam casting patterns is casting using a pattern of materials that can evaporate when exposed to molten metal heat. Casting uses a temperature of 650°C, 700°C, 750°C, 800°C. The results of casting temperature can affect porosity, microstructure, and hardness.

Abstract

The second largest metal material used after steel is Aluminum and its alloys. Ranging from aircraft bodies, vehicles, engine components, ship components, to buildings and very diverse applications using aluminum alloys. Material for making alloy wheels for components in motors using one of the special aluminum alloy applications with regard to the strength and hardness of high-quality aluminum alloys. Industrial companies that make aluminum doors, including windows and frames, make aluminum shelves, storefronts and other products. Produce waste remnants of used aluminum which can be used as aluminum as the main material destination. To reduce the company's production costs, many of them use aluminium scrap as their main casting material. Casting uses a temperature of 650 ° C, 700 ° C, 750 ° C, 800 ° C including casting type evaporative or casting using Styrofoam. The missing styrofoam casting pattern is a casting that uses a pattern of material that can evaporate when exposed to molten metal heat. The casting temperature results can affect microstructure, hardness, porosity and structure.
