Helical Coil Metals
We can engineer, design, size and manufacture your coils out of 24 different types of metals and alloys. Our shop carries the AMSE “U”, “UM”, “R” and NB certification stamps. We are a ASME Code Section VIII, Division 1 shop with the engineering and manufacturing capabilities to produce any type and size coil that you may need. Since 1983 we have built a strong reputation for providing high quality products at competitive pricing for a wide range of industries including Areospace, Boiler Repair, Chemicals, Electronics, Hospitals, Housing, Paper, Petroleum and pharmaceuticals. Below is a list of metals that we have the ability to manufacture coils with.
Stainless Steel Coils
Stainless steel coils can be offered in 304-L, 316-L, 317-L, & 321-L stainless steel. See below metals for specifications.
Admiralty Brass Coils
Admiralty brass contains 30% zinc, and 1% tin which inhibits dezincification in many environments. Brass has higher malleability than bronze or zinc.
Carbon Steel Coils
Carbon steel is steel where the main interstitial alloying constituent is carbon. As the carbon content rises, steel has the ability to become harder and stronger through heat treating.
Copper Coils
Copper and copper alloys are some of the most versatile engineering materials available. The combination of physical properties such as strength, conductivity, corrosion resistance, machinability and ductility make copper suitable for a wide range of applications.

304-L Stainless Steel Coils
304 is the standard “18/8” stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other.
316-L Stainless Steel Coils
316-L has better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments.
317-L Stainless Steel Coils
Grade 317 stainless steel is a modified version of 316 stainless steel. It has high strength and corrosion resistance. Grade 317 stainless steel is tougher than 304 stainless steel.
321-L Stainless Steel Coils
321 has the basic austenitic 18/8 steel (Grade 304) stabilised by Titanium or Niobium. This grade is used because it is not sensitive to inter-granular corrosion after heating.
Copper Coils
Copper and copper alloys are some of the most versatile engineering materials available. The combination of physical properties such as strength, conductivity, corrosion resistance, machinability and ductility make copper suitable for a wide range of applications.
Alloy 20 Coils
Alloy 20 is a nickel-chromium-molybdenum stainless steel alloy developed for applications involving sulfuric acid. Its corrosion resistance also finds other uses in the chemical, food, pharmaceutical, and plastics industries.
Inconel 600 Coils
Inconel 600 is a Nickel-Chromium alloy with good resistance to oxidation and corrosion at high temperatures. When heated, Inconel forms a thick, stable, passivating oxide layer protecting the surface from further attack.
Inconel 825 Coils
Inconel 825 is a Nickel-Iron-Chromium alloy with additions of Molybdenum and Copper. It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking and to localized pitting and crevice corrosion.
Monel 400
Monel 400 is a Nickel-Copper alloy with high strength and excellent corrosion resistance in a range of acidic and alkaline environments and especially suitable for reducing conditions. It also has good ductility and thermal conductivity.
Admiralty Coil
Admiralty brass contains 30% zinc, and 1% tin which inhibits dezincification in many environments. Brass has higher malleability than bronze or zinc.
Hastelloy C Coils
Hastelloy C-276 is a Nickel-Molybdenum-Chromium alloy with the addition of Tungsten, has excellent corrosion resistance in a wide range of corrosive media and is especially resistant to pitting and crevice corrosion.
Hastelloy B Coils
Hastelloy B is a wrought nickel-molybdenum alloy that can be used in the ‘as welded’ condition. This alloy has excellent resistance to all temperatures and concentrations of hydrochloric acid.
Titanium Coils
Titanium alloys are metals which contain a mixture of titanium and other chemical elements. Such alloys have very high tensile strength and toughness (even at extreme temperatures).
Aluminum Coils
Aluminum properties include good appearance, ease of fabrication, good corrosion resistance, low density, high strength-to-weight ratio and high fracture toughness.
Nickel 90/10 Coils
Copper-nickel alloy with an alpha phase structure. Small amounts of iron and manganese are added to improve corrosion resistance in high-velocity (from 1 to about 3.5 m/s) waters,
including seawater.
Nickel 70/30 Coils
The 70/30 copper nickel alloys have great resistance to sea water-related corrosion due to the presence of significant amounts of manganese and iron. Their high oxidation resistance is seen in moist air and steam.
Nickel 80/20
The 80/20 Copper-nickel alloys have very good resistance to biofouling and marine corrosion, and possess good fabricability. Copper gains more strength and corrosion resistance when nickel is added to it.
Nickel 200 Coils
Nickel with good mechanical properties over a wide range of temperature and excellent resistance to many corrosives, in particular hydroxides. Good resistance to corrosion in acids and alkalis and is most useful under reducing conditions.
Duplex 2205
Duplex 2205 stainless is a mixed microstructure of austenite and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades with similar corrosion resistance qualities.
Duplex 2507
SuperDuplex stainless like Duplex, is a mixed microstructure of austenite and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades.
AL 6X N Coils
AL-6XN alloy is a superaustenitic stainless steel. It exhibits far greater resistance to chloride pitting, crevice corrosion and stress corrosion cracking.
