Materials We Work With
No matter how difficult the part or material is, we are here to help you design and machine each part from start to finish. Our team crafts precision parts that push the envelope of standard machining quality.
Titanium
Titanium is strong yet extremely lightweight. Because of its easy-to-clean and biocompatible properties, it is a popular metal for use in medical and healthcare applications.
Plastics
Plastics are present in almost every industry today, replacing more expensive parts for with an affordable alternative.
Aluminum
An affordable and lightweight material, aluminum is also known for its resistance to corrosive materials. While not as durable and hard as steel or titanium, it is extremely easy to machine, making it a popular choice for quality parts.
Stainless Steel
Used in various industries, stainless steel is excellent for corrosion resistance, strength, and durability. This material is popular for demanding applications that need resistance to rust or acidic environments.
Molybdenum
As a popular material for aerospace, energy, and electronics industries, this metal is known for its heat and corrosion resistance. It has a high tensile strength similar to steel, but it can be difficult to machine so it is not as widely available.
Ductile Iron
Ductile iron is a popular choice for its resistance to wear and tear. It is highly machinable, making it a popular choice. Providing the strength and durability of cast iron, this metal is treated with magnesium to make it more ductile and flexible.
Cast Iron
This is a strong, durable material that can withstand a large amount of stress and wear during everyday use, while remaining machinable enough to use it for complex parts. Cast iron and ductile iron are materials that few shops handle because of its dustiness and difficult handling, however, Mountain Machine Works has processes in place to manage these problems, making these materials a breeze to work with.
Super Alloys and Special Metals
When your project demands advanced performance in extreme conditions—whether it’s heat, corrosion, or strength—super alloys and special metals deliver exceptional results.
