TECHNOLOGY OVERVIEW

Basic Knowledge of CNC Machining Metals

What are Metals?

 

Metals are a group of elements known for their unique characteristics. They're excellent conductors of electricity and heat, can be shaped without breaking (malleability), and stretched into thin wires (ductility). Metals have a shiny appearance, called metallic luster, and are typically solid at room temperature. Their atoms are arranged in a crystal lattice structure, forming a "sea of electrons" that enables electrical conductivity. Common metals include iron, aluminum, copper, gold, and silver. These materials are used in various industries due to their excellent properties, contributing to advancements in construction, electronics, and transportation.

An alloy is a mix of two or more elements, including at least one metal, with a variable or fixed composition. Combining metals as alloys enhances their properties, making them less brittle, harder, corrosion-resistant, or with improved color and luster. Iron alloys, like steel and stainless steel, dominate in quantity and commercial value. Different ratios of metals produce variations like low-, mid-, and high-carbon steels. Other significant alloys include those of aluminum, titanium, copper, and magnesium, each valued for specific qualities, such as high strength-to-weight ratios.

FAQ

CNC Machining Metals Buying FAQ

CNC machining can be applied to various metals, including aluminum, steel, stainless steel, brass, copper, and titanium.
CNC machines are not typically used for welding. Welding is a separate process that joins metals by melting and fusing them together, whereas CNC machining involves cutting, milling, or drilling.
Titanium is often considered one of the most difficult metals to machine due to its high strength, low thermal conductivity, and chemical reactivity.
Aluminum is one of the easiest metals to machine due to its softer and more malleable properties than other metals like titanium or stainless steel.
