Guide

Copper is widely used in electrical, thermal, and industrial components. At room temperature, the density of copper is approximately 8.96 g/cm³ (8,960 kg/m³). You can use this value to estimate CNC part weight and the mass of material needed for machining. This guide explains copper density units, compares common grades and metals, and shows you how to measure density.

Soft metals have relatively low hardness, making them easier to scratch, indent, or permanently deform. Common examples include cesium, lead, tin, gold, silver, pure aluminum, and pure copper.

Silver is a common precious metal widely used in jewelry and electronics. This guide introduces you to the melting point of silver across different types and alloys, the factors that affect it, and the silver-melting process, helping you understand the role of temperature control in casting, joining, and recycling.

Gold (Au) is a precious metal that melts at approximately 1,064°C (1,948°F) in its pure form. Gold alloys, such as 18K and 14K gold, melt at different temperatures depending on their composition. This guide covers gold melting temperatures, the equipment used to melt gold, and why the material’s composition matters.
