Alloy Steel, Carbon Steel
Different types of Alloy Steel
Alloy steel(*Ref 1.) is kind of carbon steel that is alloyed with a variety of elements in order to improve its mechanical properties. For example, strength, hardness, toughness, wear resistance, corrosion resistance and hardenability. Heat treatment may be required to achieve some of above improved properties.

Different types of Carbon Steel
Frankly speaking, carbon steel(*Ref 2.) is kind of steel with carbon content less than 2.1% by weight. Actually, we can generally use the term "carbon steel" to describe steel which is not stainless steel. As the carbon content increases, carbon steel is with better machinability able to get harder and stronger with heat treating treatment, but becomes less ductile.
AISI 12L14 (JIS SUM24L, DIN 9SMnPb36, free cutting steel)

Available in square, round, and hexagon form. Generally used for shafts, bolts, valves, bushings, pins, fittings, machine screw, surgical and dental procedures utensils, certain automobile parts, instruments, etc.
AISI 1215 (JIS SUM23, DIN 9SMn36, free cutting steel)
AISI 1215 are resulphurized and rephosphorized free machining steels with excellent machinability. It forms small chips when machined. Nickel plating, chrome plating, zinc plating on 1215 steel are helpful for anti-corrosion. Mainly supplied for heavily machined components and parts subject to low stress levels, low shock loading.
AISI 1015 (JIS S15C)
One of mostly used low carbon steel. Lower strength compare to medium carbon steel, but good toughness, weldability, punching press properties. AISI 1015 is often used for manufacture of chain, rivets, bolts, shaft.

One of often used medium carbon steel, contained Sulfur to enhance its machinability, so called free cutting medium carbon steel. Also featured with good wear-resistance and high strength. Mainly supplied for transmission components, such like gears, shafts, bolts, valves, bushings, pins, fittings, spring seat and machine screw, surgical and dental medical components, automobile parts, industrial instruments spare parts, etc.
JIS SK4 (SK95)
Contained 0.9-1.0% carbon by weight ratio, so called high carbon tool steel with great toughness, high strength and good wear-resistance. High hardenability, can be tempered to hardness at least HRC 62, less deformation in quenching. Generally used in a wide range of industrials including regular springs, spiral springs, knitting needles, horns, measuring tapes, pins, shafts, plug gauges and washers.
JIS SK5 (SK85, spring steel)
Contained 0.8-0.9% carbon by weight ratio, one of most common high carbon tool steel with great toughness, high strength and good anti-corrosion. High hardenability, can be tempered to hardness at least HRC 62, less deformation in quenching. Tempering treatment is required to improve springiness of machined parts made of JIS SK5. Generally supplied for industrial components such like automobile parts, blades, regular springs, clips, washers.
JIS SK7 (SK65, spring steel)
Contained 0.6-0.7% carbon by weight ratio, one of most common high carbon tool steel. High hardenability, can be tempered to hardness at least HRC 59, less deformation in quenching. Tempering treatment is required to improve springiness of machined parts made of JIS SK7. Generally supplied for industrial components such like automobile parts, coil springs, clip springs, washers.

Aluminum Alloy
CNC machining aluminum part featured with economical, light weight and attractive is one of our core CNC machining service. Parts made from aluminum alloy(Ref*) are often less expensive because they can be machined in less time than many other metals such as steel. Although CNC machining aluminum parts do not require additional finishes, we can also supply anodized aluminum parts with various colors. Plain aluminum is resistant to corrosion as a thin protective layer is formed when exposed to the atmosphere.
Aluminum is with good machining condition, and has a high strength to weight ratio. It is also a good conductor of electricity and heat, making it ideal for heat sinks.

Tips of Choosing Material
It is challenge to decide on the best material for your CNC machined part. Generally speaking, there are various factors to make the decision. For instance, price, hardness, tolerance, environment, surface treatment, etc.
Below are some tips:
- Metals allow cnc machining parts with better tolerance than plastics.
- Plastics is lighter, but could deform slightly over time due to moisture absorption.
- Parts made by sheet metal is generally lower cost than machining from plate or rod.
- Materials that don't need finishing may be more economical for fastest production (e.g. stainless steel, plastics, titanium, etc.)
