1: Brief Introduction Of 2017 Aluminium/Aluminum Round Bar 

Aluminium/aluminum 2017 alloy is a heat treatable wrought alloy with intermediate strength. It is stronger than aluminium /aluminum 2011, but harder to machine. Workability is fair with ductility and formability better that aluminium / aluminum 2014. Arc and resistance weldability of this alloy are satisfactory while corrosion resistance is fair.
Machinability and formability:
Aluminium / aluminum 2017 alloy has excellent machinability in the T4 temper. It is recommended that oil lubricants be used for all machining operations. Likewise formability is excellent especially in the annealed condition.
Welding:
Welding tends to reduce corrosion resistance, hence should be avoided whenever possible. If welding is required, heat treatment should be performed after welding to restore corrosion resistance. The preferable welding techniques are inert gas welding and resistance welding.
Annealing:
Aluminium / aluminum 2017 alloy can be solution annealed at 504°C (940°F) for 3-4h followed by water quenching. Age hardening is performed at room temperature and this produces the T4 temper. Cold working such as shaping and bending, can be easily performed by using traditional methods. Annealing can be performed at 413°C (775°F) for 3 h and then controlled cooling at 10°C (50°F)/h down to 260°C (500° F). Finally, it can be air-cooled.
Aging:
Aluminium/aluminum 2017 alloy ages normally at room temperature to produce optimum mechanical properties. Similarly, it is age hardenable at room temperature.
Applications:
Aluminium/aluminum 2017 alloy is chiefly used in the following products:
Screw machine products and fittings
Pulleys and gauges
Coat hangers
Crochet and knitting needles
Rivets
General structural components
Components in the transportation sector
Fasteners
Aircraft components

2: Chemical Composition  



The aluminum industry has created a system using a four-digit numerical designation to identify wrought aluminum alloys.  The first digit indicates the major alloying element.  The second digit indicates whether there was a modification in the basic alloy.  The third and fourth digit indicates the specific alloy.  The following represent the various groups:
Aluminum Grades:
1000 series: 1035,1040,1050,1060,1070,1080,1090,1098,1100,1230,1435,1260,1170,1275,1285,1385
2000 series: 2001,2002,2011,2014,2017,2117,2218,2519,2024,2224,2025,2030,2031,2036,2090,2091
3000 series: 3002,3003,3004,3103,3203,3303,3105,3006,3007,3107,3008,3009,3015,3016
5000 series: 5005,5205,5006,5010,5013,5014,5016,5017,5040,5043,5050,5150,5251,5351,5451,5052,5083
