Inquiry:

1, drawings: you need to provide copper Cast drawings, drawings, drawings or samples, any one can be. (These are the first prerequisites for our service, but also an important criterion for the acceptance of the workpiece after you have done the workpiece, so please be sure to provide it. )

2, the number: you need to customize the number of copper castings (the more the number, the more favorable price Oh!)

3, Material: copper (Which is the national standard or the corporate standard or the export of American standards, please specify. These will affect the price to a lot of Oh!)

4, duration: This is also an important information, if you want to be very urgent, will increase manufacturing costs, the general casting of the manufacturing cycle is 8 days. (If there is no model will be model manufacturing time, get the drawings arranged for half a day, One day, drying the core one day, melting the copper water to cast one day, sanding the sand to clean the castings one day, the rough processing day, refining the processing day, the milling slot drilling day, the packaging is shipped for half a day.

Note: Due to the uncertainty of the casting, the time is the shortest time of success. If there is any delay in the case of scrap or test model and too many orders, please contact us according to the actual situation.

Aluminum bronze: aluminum as the main alloying elements of copper-based alloy called aluminum bronze. Aluminum bronze mechanical properties than brass and tin bronze high.Apply the application of aluminum bronze aluminum content of 5% to 12%, with aluminum 5% to 7% of aluminum bronze plastic is good, suitable for cold processing use.Aluminum content greater than 7% to 8%, the strength increases, but the plastic plummeted, so more in the as-cast or after the use of thermal processing. Abrasive and corrosion resistance in the atmosphere, seawater, seawater carbonic acid and most organic acids are higher than brass and tin bronze, aluminum bronze can manufacture gears, bushings, worms and other high-strength anti-wear parts and high corrosion resistance Elastic component, the main grade is ZCuAl10Fe3.

ZQAl9-4 aluminum bronze Chemical composition:

Copper Cu: the rest

Lead Pb: ≤0.02 (impurity)

Ni: 4.0 to 5.0

Aluminum Al: 8.5 to 10.0

Iron Fe: 4.0 to 5.0

Mn: 0.8 to 2.5

Silicon Si: ≤ 0.15 (impurity)

Carbon C: ≤0.10 (impurity)

Note: The sum of impurities ≤ 1.0

QAl9-4 is iron-containing aluminum bronze, high strength and friction reduction, good corrosion resistance, good pressure in the hot workability, welding and gas welding, but poor weldability, QAl9-4 aluminum Bronze can be used as a substitute for high tin wearable bronze.

This product uses advanced production technology - centrifugal casting, produced by the copper sleeve, bearing and sand compared to significantly improve the compactness of the casting, wear resistance, with good tensile strength, flexural strength and elongation , But will not appear as sand-like castings such as sand holes and other phenomena, is a lot of mechanical products supporting the use of choice. 9-4 copper material characteristics of high hardness, excellent wear resistance, easy to produce bite the phenomenon, Casting performance and machinability, good corrosion resistance in both atmospheric and fresh water. For wear parts that work at high loads (20 MPa or less) and at high slip speeds (8 m / s), such as connecting rods, bushings , Bearing, gear, worm and so on.
