6061 (Unified Numbering System (UNS) designation A96061) is a precipitation-hardened aluminium alloy, containing magnesium and silicon as its major alloying elements. Originally called “Alloy 61S”, it was developed in 1935.[2] It has good mechanical properties, exhibits good weldability, and is very commonly extruded (second in popularity only to 6063).[3] It is one of the most common alloys of aluminium for general-purpose use.

It is commonly available in pre-tempered grades such as 6061-O (annealed), tempered grades such as 6061-T6 (solutionized and artificially aged) and 6061-T651 (solutionized, stress-relieved stretched and artificially aged).

The mechanical properties of 6061 depend greatly on the temper, or heat treatment, of the material.[5] Young’s Modulus is 69 GPa (10,000 ksi) regardless of temper.[6]


Annealed 6061 (6061-O temper) has maximum ultimate tensile strength no more than 150 MPa (22 ksi),[7][8] and maximum yield strength no more than 83 MPa (12 ksi)[7] or 110 MPa (16 ksi).[8] The material has elongation (stretch before ultimate failure) of 10–18%. To obtain the annealed condition, the alloy is typically heated at 415 °C for 2-3 hours.[9]


T4 temper 6061 has an ultimate tensile strength of at least 180 MPa (26 ksi)[8] or 210 MPa (30 ksi)[7] and yield strength of at least 110 MPa (16 ksi). It has elongation of 10-16%.


6061-T6 aluminium standard heat treating process

T6 temper 6061 has been treated to provide the maximum precipitation hardening (and therefore maximum yield strength) for a 6061 aluminium alloy. It has an ultimate tensile strength of at least 290 MPa (42 ksi) and yield strength of at least 240 MPa (35 ksi). More typical values are 310 MPa (45 ksi) and 270 MPa (39 ksi), respectively.[10] This can exceed the yield strength of certain types of stainless steel.[11] In thicknesses of 6.35 mm (0.250 in) or less, it has elongation of 8% or more; in thicker sections, it has elongation of 10%. T651 temper has similar mechanical properties. The typical value for thermal conductivity for 6061-T6 at 25 °C (77 °F) is around 152 W/m K. The fatigue limit under cyclic load is 97 MPa (14 ksi) for 500,000,000 completely reversed cycles using a standard RR Moore test machine and specimen.[12] Note that aluminium does not exhibit a well defined “knee” on its S-N curve, so there is some debate as to how many cycles equates to “infinite life”. Also note the actual value of fatigue limit for an application can be dramatically affected by the conventional de-rating factors of loading, gradient, and surface finish.

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.

Q.What is a standard used in pipe fittings?
