Arsenic brass wire is a copper-zinc alloy wire containing a controlled addition of arsenic. It is developed to provide a combination of mechanical strength, ductility, machinability, and improved resistance to dezincification and corrosion in suitable environments.
Arsenic-added brass is available in different alloy compositions and product standards. Depending on the specific grade, it can be supplied as wire, strip, sheet, tube, or other semi-finished products. Arsenic brass wire is particularly useful where good forming performance and corrosion resistance are required. :contentReference[oaicite:0]{index=0}
The controlled arsenic addition can help improve the corrosion performance of brass, particularly resistance to dezincification. Different grades may provide different combinations of strength, ductility, machinability, and forming performance.
One of the main purposes of adding a controlled amount of arsenic to certain brass alloys is to improve resistance to dezincification. Dezincification is a form of corrosion in which zinc is selectively removed from brass, potentially leaving behind a porous copper-rich structure.
Arsenic-containing dezincification-resistant brass grades use a carefully controlled alloy composition to reduce this corrosion mechanism. The exact performance depends on the alloy grade, manufacturing condition, environment, and applicable standard. :contentReference[oaicite:1]{index=1}
CuZn30As is a 70/30 arsenical brass grade containing approximately 70% copper with a controlled arsenic addition. It is associated with applications requiring improved resistance to dezincification and is available in various semi-finished product forms.
C26130 is an arsenical brass designation used for certain brass products. Depending on the applicable product standard, it can be supplied in wire and other forms for industrial applications.
C44300 is an arsenical Admiralty Brass grade containing copper, zinc, tin, and a controlled arsenic addition. It is primarily associated with condenser and heat-exchanger tubing rather than general-purpose wire, so the correct product form and standard should always be confirmed before ordering.
Arsenic brass wire is generally produced through a controlled sequence of alloy preparation, casting, hot working, drawing, heat treatment where required, and final inspection.
For smaller wire diameters, intermediate annealing may be used during drawing to maintain the required combination of ductility and dimensional accuracy. :contentReference[oaicite:2]{index=2}
Arsenic brass wire can be used in industrial manufacturing and engineering applications where corrosion resistance, mechanical performance, and reliable forming characteristics are required.
Arsenic brass wire can be supplied in different diameters, tempers, surface conditions, and packaging formats according to customer requirements.
Some commercial suppliers list arsenic brass wire in diameters such as 0.5–2.5 mm and offer customized sizes, although the available range depends on the manufacturer and alloy grade. :contentReference[oaicite:3]{index=3}
The alloy grade should be selected according to the required corrosion resistance, mechanical properties, forming process, and final application.
Choose the wire diameter according to the finished component, forming process, dimensional tolerance, and required mechanical performance.
Annealed wire provides higher ductility, while harder tempers can provide increased strength. The appropriate temper should be selected according to the manufacturing process.
Surface requirements depend on the final application. Bright, polished, oiled, brushed, and other finishes may be available depending on the supplier.
Always specify the required ASTM, EN, JIS, BS, GB, or other applicable standard to ensure that chemical composition and mechanical properties are properly controlled.
The main difference is the controlled addition of arsenic in specific arsenical brass grades. Standard brass may not contain arsenic as an intentional alloying element, while arsenic brass is formulated to achieve particular corrosion-performance characteristics.
Arsenic brass should not be treated as a single universal alloy because composition, properties, and applications vary between grades. Buyers should specify the exact alloy designation and applicable product standard rather than ordering only by the general term "arsenic brass wire."
Professional manufacturers use comprehensive quality-control procedures to verify chemical composition, dimensions, mechanical properties, and surface quality.
A professional manufacturer can control alloy composition, wire drawing, heat treatment, dimensional tolerances, and surface quality throughout the production process.
An experienced supplier can also provide customized wire diameters, tempers, surface finishes, packaging, material certificates, and inspection documentation according to customer requirements.
For industrial procurement, confirming the exact alloy designation and applicable standard with the manufacturer is important because different arsenical brass grades can have significantly different compositions and intended applications.
Arsenic brass wire is used for various industrial and engineering applications requiring a combination of mechanical performance, ductility, machinability, and improved corrosion resistance.
A controlled arsenic addition can improve resistance to dezincification in suitable brass alloys. The effect depends on the alloy composition and processing condition.
Yes. Wire diameter, temper, surface finish, packaging, and applicable material standard can be customized according to project requirements.
Depending on the alloy and product form, manufacturers may work to ASTM, AISI, JIS, ISO, EN, BS, GB, and other applicable standards.
No. Admiralty Brass is a specific family of copper-zinc-tin alloys, with arsenical grades such as C44300. "Arsenic brass" is a broader description covering brass grades that contain a controlled arsenic addition.
For accurate quotation and production, provide the alloy designation, wire diameter, tolerance, temper, surface finish, required quantity, standard, packaging requirements, and intended application.
Arsenic brass wire is a specialized copper alloy product designed to combine the useful mechanical and processing characteristics of brass with improved corrosion performance in appropriate alloy grades. It is available in different compositions, dimensions, tempers, and surface finishes for industrial applications.
For reliable procurement, buyers should select the exact alloy grade and applicable standard according to the operating environment and manufacturing requirements. Working with an experienced arsenic brass wire manufacturer can help ensure consistent chemical composition, dimensional accuracy, mechanical performance, and product quality.
