Heat Treatment Steps of Brass Union Fitting
The production process of brass union fittings is similar to that of brass ball valves. Both require the brass rods to be cut and then heated. When a certain temperature is reached, the internal organisation of the brass bar changes, at which point the shape is fixed by hot forging. Finally the edges are cut and shot blasted.

At D&R, we have the widest selection for compression union fittings. Our wide range of brass union fittings include brass pipe union connector, male brass union fittings, brass compression tube fittings, brass bulkhead union fittings, and more.
Our compression union fittings are meticulously designed with tight and high-quality threads. It allows for a secure fitting without slipping. Its deep thread is also designed specifically for enhancing fixation and meshing.
D&R brass union fittings also have smooth threads. Thus, you can easily and quickly install it. These are also manufactured using the best quality brass materials. With these lead-free materials, you can assure that your compression union fittings have high strength, corrosion resistance, good quality, high-temperature resistance, and high hardness.
General brass is a Cu-Zn binary alloy, Zn can be dissolved in Cu in large quantities to form α solid solution (face-centred cubic lattice, good plasticity), the maximum solubility at room temperature up to 39%, more than this content is β′ phase (body-centred cubic lattice) formation. β′ phase for CuZn compounds based on the orderly solid solution, hard and brittle, so the mechanical properties of brass and The amount of Zn is very relevant. The Zn content of brass for industrial use generally does not exceed 47% and is organised as α or α+β′, called α brass or α+β′ brass respectively.
Alpha brass, also known as single-phase brass, has low strength and particularly good plasticity and is suitable for cold pressure processing of cold rolled sheets, cold drawn wire, pipe fittings and deep pressed parts. Commonly used codes are H80, H70, H68.
α+β′ brass, also known as two-phase brass, has a high strength. Due to the high hardness of the β′ phase, the plasticity at room temperature is poor and can only withstand a small amount of deformation. The β-phase is a disordered solid solution based on CuZn compound, which is also a body-centred cubic lattice with good plasticity, so α+β′ brass is suitable for hot processing, and it is even easier to deform than α brass when it is higher than 800°C. It is often hot rolled into bars, tubes and plates. Commonly used code H59, H62, used as water pipes, oil pipes, radiators, etc.
- Al brass: The main function of Al is to improve the strength, hardness and corrosion resistance of brass.
- Sn brass: The main role of Sn is to improve the corrosion resistance of brass in the marine atmosphere and seawater, but also to improve the strength of brass.
- Mn brass: The main role of Mn is to improve the strength and heat resistance of brass as well as the corrosion resistance in seawater and superheated steam.
- Si brass: the main role of Si is to improve the strength, wear resistance and corrosion resistance of brass, but also to improve the casting performance.
- Pb brass: The main role of Pb is to improve the machinability and wear resistance of brass.
- Ni brass: The main role of Ni is to increase the recrystallisation temperature of brass and refine its grain, improve the mechanical properties and wear resistance.
- Fe brass: the main role of Fe is to improve the recrystallization temperature of brass and refine the grain, improve the strength, toughness, wear resistance and corrosion resistance.

- Al brass is mainly used for the manufacture of marine parts such as condenser tubes, worm shafts, gears, spiral slurry etc. and other corrosion resistant parts for machines.
- Sn brass is mainly used for the manufacture of marine parts such as condenser tubes etc.
- Mn brass is mainly used for the manufacture of marine parts and wear-resistant parts such as bearings.
- Si brass is mainly used in the manufacture of marine parts and chemical machinery parts, such as bearings, valve bodies, etc.
- Pb brass is mainly used for the manufacture of valve bodies, clock parts and shaft tiles, bushings, etc. In the processing of copper valves and copper pipe fittings, various grades of lead brass are mainly used.
- Ni brass is mainly used in the manufacture of marine parts, such as condensation tubes, manometer tubes, etc.
- Fe brass is mainly used for the manufacture of parts subject to friction and seawater corrosion, such as bushings, gaskets, bearings, etc.
Carbon tool steel, alloy tool steel, high-speed steel, carbide and ceramic materials are commonly used tools in the cutting operation.
- Carbon tool steel is high-quality steel with high carbon content, which is hard and inexpensive after quenching but has poor heat resistance.
- In the carbon tool steel to add a small amount of Cr, W, Mn, Si and other elements, you can form an alloy tool steel, that can reduce heat treatment deformation and improve heat resistance.
- High-speed steel is alloyed tool steel containing more W, Cr, V, and other alloying elements.
- Cemented carbide is an alloy made of high hardness, high melting point metal carbide (WC, TiC) as a matrix, with metal Co and other binders, using powder metallurgy methods. The domestic cemented carbide is generally divided into two categories: one is the tungsten-cobalt class (YG class) consisting of WC and Co, and the other is the tungsten-titanium-cobalt class (YT class) consisting of WC and TiC.
- The main component of the ceramic material is Al2O3, with high blade hardness, good wear resistance, and high heat resistance.
