Replacing Numbers with Specific Alloys: A Comprehensive Guide
When it comes to manufacturing and engineering, the use of alloys is crucial. Alloys are materials made by combining two or more metallic elements, which can provide improved properties compared to the individual metals.
What is an Alloy?
alloy = material_1 + material_2 + ... + material_n
The resulting alloy will have enhanced properties, depending on the metals used and the proportions of each. Some common alloys include steel (iron + carbon), brass (copper + zinc), and bronze (copper + tin).
Why Replace Numbers with Alloys?
In manufacturing processes, it is common to use numbers as placeholders for specific alloys. However, referring to alloys by their actual composition provides several advantages:
- Easier communication: specifying an alloy by its name, rather than a number, reduces the risk of confusion.
- Clearer documentation: using alloy names allows for more accurate tracking of materials and processes.
- Improved safety: using alloy names can help prevent the use of incorrect or incompatible materials.
Common Alloys and Their Numbers
Here, we will cover common alloys that might be represented by numbers in manufacturing and engineering processes:
Adhesive 36 (Epoxy)
Adhesive 36 is a common epoxy used for bonding and sealing. It provides high strength, resistance to chemicals, and good electrical insulation properties. It can be replaced by the following alloys:
Araldite 2011: A two-component epoxy adhesive with high impact resistance.J-B Weld: A two-component epoxy steel-reinforced adhesive ideal for high-strength repairs.Permatex 80050: A high-strength threadlocker, suitable for securing bolts and nuts.
Refined Tungsten Alloy 4 (WC-Co)
Refined Tungsten Alloy 4 is a hard metal often used in cutting tools and wear-resistant parts. It can be replaced by the following alloys:
Tungsten Carbide with 6% Cobalt: An alternative hard metal with good toughness and wear resistance.Tungsten Heavy Alloy: A high-density alloy with excellent strength and rigidity, often used in counterweights.Tungsten Rhenium Alloy: A heat-resistant alloy commonly used in electrical contacts and furnace components.
Steel 32 (Stainless Steel 316)
Steel 32 or Stainless Steel 316 is a corrosion-resistant alloy ideal for marine and chemical applications. It can be replaced by the following alloys:
Stainless Steel 304: A general-purpose stainless steel, suitable for most applications not requiring the high corrosion resistance of Steel 32.Duplex Stainless Steel: A two-phase stainless steel with higher strength and improved corrosion resistance compared to Steel 32.Super Duplex Stainless Steel: A high-strength, corrosion-resistant stainless steel suitable for seawater and acidic environments.
Refined Tungsten Alloy 376 (WC-Co)
Refined Tungsten Alloy 376 is a hard metal with excellent toughness often used in mining applications. It can be replaced by the following alloys:

Thread 24 (M24x1.5)
Thread 24 or M24x1.5 is a metric thread size commonly used in machinery and equipment. It can be replaced by the following thread sizes:
M22x1.5: A metric thread size with a slightly smaller diameter.M27x1.5: A metric thread size with a slightly larger diameter.1-1/16-18 UNC: A corresponding imperial thread size.
Refined Aluminium Alloy 5 (AlSi7Mg)
Refined Aluminium Alloy 5 or AlSi7Mg is a casting alloy with high strength, good thermal conductivity, and excellent castability. It can be replaced by the following alloys:
AlSi9Cu3: A casting alloy with good strength and ductility.AlSi12: A casting alloy with excellent castability and good mechanical properties.AlMg5: A wrought alloy suitable for extrusions and forgings with good formability and strength.
