Materials Selection & Processes
LEADRP has extensive experience working with different materials and different manufacturing processes. We help our customers choose the right materials to achieve exact dimensions with tight tolerances. We can produce complex parts with extremely high consistency and repeatability that meet your requirements for application and performance(like hardness, strength, density, and thermal properties, ).

Metal and Alloy Materials
We know every project has unique requirements and properties; we offer a wide variety of metals, including Aluminum, Hot-Rolled Steel, Cold-Rolled Steel, Stainless Steel, Alloy Steel, Galvanized Steel, Tool Steel, Brass, Bronze, and Copper. Our experienced engineer will find suitable metal & alloy materials and machining solutions for your project.
Alloy steel contains small 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.
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 one of the most versatile metals, and they have beneficial properties like corrosion resistance, high thermal conductivity, and very high electrical conductivity. 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 various 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, aluminum is widely used in aerospace, transportation, architecture, food, and chemical handling (cookware, pressure vessels, etc.).
LEADRP offers a complete Aluminum CNC machining service and can produce custom Aluminum parts in a variety of shapes and grades, including 1100, 2011, 2024, 3003, 4017, 5052, 6061, 6063, and 7075.
Titanium alloys are alloys composed of titanium and other chemical elements. Titanium alloys are light in weight, have incredibly high tensile strength and toughness, are extremely corrosion resistant, and withstand extreme temperatures.
Titanium alloys are widely used in military applications, aircraft, spacecraft, bicycles, medical devices, jewelry, high-stress components such as connecting rods on high-end sports cars, and some premium sports equipment and consumer electronics.
LEADRP offers a complete Titanium CNC machining service and can produce custom Titanium parts in various shapes and grades, including Titanium Grade 1, Titanium Grade 2, and Titanium Grade 5.
