Applications and Specialties of Al Metal
Al Metal is known for its wide range of fastening materials, both standard and specialized. From standard steel grades to advanced alloys and stainless steel (SS), we supply fasteners for a wide variety of applications. Below is an overview of the materials we offer, with specific applications to demonstrate how each material contributes to reliable and durable fastening solutions.
Steel (4.6 / 5.6 / 8.8 / 9.8 / 10.9 / 12.9 / 14.9)
Application: General construction and machinery
Steel in various strength grades is commonly used in construction and machinery due to its good load-bearing capacity and durability. Grade 8.8 is often used for medium-heavy constructions like steel frames, while grades 10.9 and 12.9 are ideal for higher-load applications, such as motor mountings and heavy machines. For more demanding applications, we offer grade 14.9, for example, for critical connections in the automotive industry.
Stainless Steel A2 / A4 / A5
Application: Hydraulic, food industry, and outdoor constructions
Stainless steel, especially grades A2 (standard stainless steel), A4 (acid- and seawater-resistant), and A5, is ideal for applications that need to withstand moisture and chemical influences. A2 is often used in the food industry, while A4 is suitable for marine and coastal areas due to its high corrosion resistance. A5 is used in specific chemical processes.
Duplex Stainless Steel (A6)
Application: Heavy industrial and chemical installations
Duplex stainless steel, or A6, combines high strength with excellent corrosion resistance, making it ideal for heavy industrial applications. Fasteners made from duplex stainless steel are commonly used in chemical plants and offshore projects, where corrosion resistance and strength are crucial.
Stainless Steel 1.4529 (A8) / 1.4539
Application: Extreme chemical environments and water treatment plants
Stainless steel 1.4529 (A8) and 1.4539 are super austenitic steels specifically developed for environments with high corrosion demands, such as water treatment plants and chemical factories. These materials offer optimal protection against chlorides and acids and are used in fasteners for installations that are exposed to aggressive substances for long periods.
Stainless Steel 309 and 310
Application: High-temperature applications such as ovens and power plants
Stainless steel 309 and 310 are specifically designed for high-temperature applications. With their excellent oxidation and heat resistance, these materials are perfect for fasteners in ovens, power plants, and industrial boilers. They maintain their strength and corrosion resistance at temperatures up to 1,100 °C.
Aluminium
Application: Lightweight constructions and aviation
Aluminium is lightweight, corrosion-resistant, and easy to process, making it ideal for applications where weight is important, such as in aviation and light construction. Aluminium fasteners are perfect for applications that do not require heavy loads but need durability and corrosion resistance.
Titanium (Grade 2 / Grade 5 / Grade 7)
Application: Aerospace, medical applications, and offshore
Titanium is known for its unparalleled strength-to-weight ratio, combined with excellent corrosion resistance. Grade 2 is pure titanium and is used for applications that mainly require corrosion resistance, such as in seawater environments. Grade 5 is a titanium alloy with additional strength, ideal for aerospace, while Grade 7 is suitable for chemical environments due to its high corrosion resistance.
Hastelloy
Application: Extremely corrosive chemical environments
Hastelloy is a nickel alloy that is exceptionally resistant to a variety of aggressive chemicals. It is widely used in fastening materials for the chemical industry, where fasteners must withstand both high temperatures and highly corrosive substances. Ideal for heavy chemical processes and industrial installations.
Inconel
Application: High-pressure and high-temperature applications
Inconel is a nickel-chromium alloy that performs excellently under high pressure and temperatures, often used in aerospace and energy production. Inconel fasteners are oxidation-resistant and maintain their strength at extreme temperatures, making them suitable for applications such as turbines and engine parts.
Monel
Application: Maritime applications and oil and gas extraction
Monel is a nickel alloy with exceptional corrosion resistance, especially against seawater. It is widely used in fastening materials for maritime applications such as shipbuilding and offshore oil and gas installations. Monel is particularly resistant to saltwater environments and provides reliable performance in wet, corrosive environments.
Copper (CU5)
Application: Electrical applications and heat exchangers
Copper provides excellent electrical conductivity and is widely used in fastening materials for electrical applications and heat exchangers. In situations where conductivity and thermal properties are important, such as in electronics and energy industries, copper is the ideal choice for fasteners.
Super Duplex
Application: Heavy offshore installations and chemical environments
Super Duplex is a very strong, corrosion-resistant alloy that is frequently used in offshore and heavy industrial environments. With its high resistance to pitting and stress corrosion, Super Duplex is ideal for fasteners in maritime and chemical applications where long life and reliability are essential.
