3003 aluminium alloy is an alloy in the wrought aluminium-manganese family (3000 or 3xxx series). It can be cold worked (but not, unlike some other types of aluminium alloys, heat-treated) to produce tempers with a higher strength but a lower ductility. Like most other aluminium-manganese alloys, 3003 is a general-purpose alloy with moderate strength, good workability, and good corrosion resistance. It is commonly rolled and extruded, but typically not forged. As a wrought alloy, it is not used in casting. It is also commonly used in sheet metal applications such as gutters, downspouts, roofing, and siding.

 Material Grade:
1100 – This low-strength alloy has excellent corrosion-resistance, has satisfactory anodizing and conversion coating finishing characteristics,3003 – Excellent workability rating. May show some slight discoloration when anodized, but reacts well to mechanical and organic finishings. Is easily welded and brazed, but soldering is limited to the torch method.5005 – Excellent corrosion-resistance and weldability, but would rate somewhat below 1100 and 3003 for brazing and soldering, and it is not the alloy one would choose for machinability. Typical end uses are decorative trim, utensils, mobile home siding and reflectors.5052 -Excellent corrosion-resistance, particularly in marine applications,Fair machining with proper set-up. Typical end uses include fuel tanks, truck-trailer side panels, small boat hulls, truck cabs, bumpers, storage tanks and pressure vessels.5083 – With excellent corrosion-resistance and weldability, together with high strength, this alloy was designed for welded structures requiring maximum joint strength and efficiency.5086 – Has excellent corrosion-resistance and weldability.

Q. What the define of pipe fittings?
Pipe fitting is the occupation of installing or repairing piping or tubing systems that convey liquid, gas, and occasionally solid materials. This work involves selecting and preparing pipe or tubing, joining it together by various means, and the location and repair of leaks.
Pipe fitting work is done in many different trades: Plumbing, HVAC, manufacturing, fire prevention, and many others. Pipe fitters (sometimes called simply “fitters”) are represented in the USA by the United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry of the United States and Canada.
Fitters work with a variety of pipe and tubing materials including several types of plastic, copper, steel, iron, aluminium, clay, and lead.

Q. What should I consider for buying pipe fittings?
A. Material, Size, Temperature and Pressure Ratings, Durability, Standards,surface coating etc.

Q. What are threaded fittings?
A. Thread fitting is the fitting with thread concetions,the regular screw standards are NPT and BSP.NPT is a U.S. standard for tapered threads used to join pipes and fitting and BSP is a family of standard screw thread types that has been adopted internationally for interconnecting and sealing pipe ends by mating an external (male) with an internal (female) thread.

Q. The define of flange?
A. A flange is usually in the shape of a plate or ring which forms a rim at the end of a pipe when fastened to the pipe our factory can produce single forge base over 8000kg.

Q.Do you provide Material Test Reports (MTR’s) ?
Relevant documents according to inspection test plan will be provide along with goods.
