CNC Machining Materials
The material is one of the most important determinants of the cost and quality of your finished product, so we’re here to help you choose wisely. When analyzing your CNC machining project requirements, it’s important to consider the properties of various materials and how they affect performance, cost, and lifespan. While some CNC machining materials are more commonly used than others, almost any metal or plastic can be machined. At LEADRP, we use a variety of metals to make the parts you need. Here is a list of our most common used materials:
CNC Metal & Alloy Materials
Alloy steel contains trace amounts of one or more alloying elements (other than carbon), such as manganese, silicon, nickel, titanium, copper, chromium, and aluminum. Alloying provides it with unique qualities not present in standard carbon steel. Due to its low cost, wide availability, ease of processing, and superior mechanical rates, alloy steel is ideal for industrial applications. In general, alloy steels are more malleable to heat and mechanical treatment than carbon steels.
LEADRP offers a complete Alloy Steel CNC machining service and can produce custom Alloy Steel parts in various shapes and grades, including 4130, 4140, 4340, and more.
Mild steel is a type of carbon steel with a low amount of carbon. It is also known as “low carbon steel.” Low carbon means it has very little carbon and other alloying elements to block dislocations in its crystal structure, resulting in less tensile strength than high carbon and alloy steels. Mild steel has good weldability and machinability, making it a popular choice for consumer products.
LEADRP offers a complete Mild Steel CNC machining service and can produce custom Mild Steel parts in a variety of shapes and grades, including Hot and Cold Rolled, Commercial Quality, Galvanized, 1018, 1020, 1026, 1020/1026, CR 1045, HR 1045, 12L14, CR 1215 and more.
Tool steel is a type of carbon alloy steel. It is frequently used to create, modify, or repair hand tools and machine dies. Tool steel is notable for its hardness, abrasion, and deformation resistance. Because steel can retain a cutting edge at extremely high temperatures, it is frequently used to shape other materials via cutting, pressing, coining, or extruding. Because of their abrasion resistance, they are commonly used in the production of injection molds. Tool steel is widely used in dies (stamping or extrusion), cutting, mold production, and impact applications such as hammers (personal or industrial).
LEADRP offers a complete Tool Steel CNC machining service and can produce custom Tool Steel parts in various shapes and grades, including A2, D2 and O1, and more.
Stainless steel is a steel alloy that is more corrosion resistant than carbon/alloy steel. Stainless steel is an iron alloy that contains at least 10.5 percent chromium. The presence of chromium results in forming a thin chromium oxide film on the surface of the steel, known as a passivation layer. This layer prevents corrosion on the steel surface; the higher the Chromium concentration in the steel, the more excellent the corrosion resistance. Stainless steel is an ideal material for food handling/processing, medical instruments, hardware, appliances, and structural/architectural products.
LEADRP offers a complete Stainless Steel CNC machining service and can produce custom Stainless Steel parts in various shapes and grades, including 17-4, 303, 304, 316, 416, 440C, and more.

Copper alloys are excellent for different industries such as electrical, construction, transport, and consumer goods. The final product made from copper includes architectural parts, coinage, condenser/heat exchangers, plumbing, radiator cores, musical instruments, locks, fasteners, hinges, ammunition components, and electrical connectors.
LEADRP offers a complete Copper CNC machining service and can produce custom Copper parts in a variety of shapes and grades, including Copper C110 and C101.
Brass is a mixture of copper and zinc. Small amounts of zinc elements are frequently added to improve specific properties. Depending on the part of zinc added to the alloy, the color of brass can range from red to yellow. Alloying can increase strength, hardness, electrical and thermal conductivity, corrosion resistance, and color. Brass is also germicidal, which means it can kill microorganisms when they contact it.
Brass is used in various applications and products, including decorative items, architectural parts, condenser/heat exchangers, plumbing, radiator cores, musical instruments, locks, fasteners, hinges, ammunition components, and electrical connectors.
LEADRP offers a complete Brass CNC machining service and can produce custom Brass parts in various shapes and grades, including Brass C260 and C360.
Aluminum is a silver-colored, low-density metal used in a wide range of commercial applications. Under most conditions, unalloyed aluminum is ductile, has moderate strength, and is highly corrosion-resistant. Appropriate alloying elements (Cu, Mg, Mn, Si, etc.) and subsequent heat/work treatments can significantly strengthen aluminum. Because of its low density and corrosion resistance is widely used in aerospace, transportation, architectural, food, and chemical handling (cookware, pressure vessels, etc.) industries.

Surface Finishing Options
Surface finish is applied to parts after they have been machined to create a unique surface layer to meet the hardness, chemical resistance, and appearance requirements of the products. It depends on material properties and the application of the part. LEADRP provides almost all types of surface finish processes.
Anodizing can improve the corrosion resistance of aluminum alloys, increase the surface hardness and wear resistance of aluminum alloys, and have a good appearance after coloring treatment. Type II traditional anodizing and Type III hard coat anodizing service is available.
Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike traditional liquid paint, which is applied with an evaporating solvent, powder coating is typically applied electrostatically and cured with heat or ultraviolet light.
Black oxide, or blackening, is a conversion coating for ferrous metals, stainless steel, copper and copper-based alloys, zinc, powdered metals, and silver solder. It produces an oxide film on the metal surface to add modest corrosion resistance, improve appearance, and reduce light reflection. Black oxide must be treated with oil or wax to provide maximum corrosion resistance.
Bead blasting produces a smooth, matte-textured surface, and sharp edges can be broken and deburred for safe handling. Bead blasting can also improve the mechanical strength, wear resistance and corrosion resistance of parts.
Electroplating is the process of coating an object in a layer of metal using electrodeposition. Electroplating is widely used to improve the surface qualities of metals, such as resistance to abrasion and corrosion, lubricity, reflectivity, and electrical conductivity. Electroplating can also make metals look better.
Polishing is a technique for creating a smooth and shiny surface by rubbing it or applying a chemical treatment. The process creates a surface with significant specular reflection, but it can also reduce diffuse reflection in some materials.
Brushing is a surface treatment process in which an abrasive belt is used to draw marks and lines on the surface of products to achieve a decorative texture.
