2017 hlin\u00edkov\u00e1 slitina<\/a> \u2014 historically known as duralumin \u2014 is one of the earliest high-strength hlin\u00edk<\/a> alloys. It delivers competitive mechanical properties at a lower cost than 2024, but the trade-off is a narrower temper window and limited corrosion resistance. This guide covers where the alloy works, where it fails, and what to check before ordering.<\/p>\n The 2017 system is Al-Cu-Mg-Mn, with copper as the primary strengthening element and magnesium contributing to the precipitation-hardening response. A typical composition range includes:<\/p>\n In the T4 temper (solution heat-treated and naturally aged), 2017 reaches tensile strengths around 390\u2013430 MPa with yield strength in the 220\u2013260 MPa range. It falls between 6061-T6 and 2024-T4 in strength \u2014 stronger than standard structural aluminum but below the aerospace-premium 2xxx grades.<\/p>\n 2017 machines cleanly and produces well-broken chips. Tool wear is moderate and generally better than 6061, but not as forgiving as the lead-containing 2011 alloy. For high-volume production, cutting speed and coolant flow should be tuned to the T4 temper response.<\/p>\n Like most 2xxx-series alloys, 2017 has limited corrosion resistance due to its copper content. Bare (unclad) 2017 is not recommended for marine, chemical, or outdoor exposure without protective coating. Alclad versions exist but are less common than for 2024.<\/p>\n Fusion welding is not recommended for 2017 \u2014 the alloy is susceptible to hot cracking and significant strength loss in the heat-affected zone. If joining is required, mechanical fastening or adhesive bonding is the safer route.<\/p>\n 2017 is precipitation-hardenable. The standard T4 temper is achieved by solution treatment at approximately 495\u2013505\u00b0C followed by quenching and natural aging. Artificial aging to T6 is possible but less common in practice because 2024 dominates that performance window.<\/p>\n 2024 is a direct upgrade: higher strength (~470 MPa UTS in T4), better fatigue performance, and wider availability in aerospace-grade sheet and plate. 2017 is the budget option \u2014 suitable where the strength margin is not critical and cost sensitivity is higher.<\/p>\n 6061-T6 offers better corrosion resistance and weldability but lower tensile strength (~310 MPa). Choose 2017 when strength matters more than weldability; choose 6061 when the part will be welded or exposed to the environment.<\/p>\n 7075-T6 delivers approximately 50% higher tensile strength than 2017-T4 but gives up machinability and is significantly more expensive. 2017 occupies the mid-range: stronger than 6061, cheaper than 7075, and easier to machine than both 2024 and 7075.<\/p>\n Use this quick reference to decide whether 2017 fits your application.<\/p>\n Go \u2014 use 2017 when:<\/strong><\/p>\n No-Go \u2014 do not use 2017 when:<\/strong><\/p>\n The Go\/No-Go criteria above cover selection logic. The list below maps specific systems where 2017 is used:<\/p>\n 2017 aluminum is a mid-range 2xxx alloy that bridges the gap between 6061 and 2024 \u2014 stronger than standard structural aluminum, cheaper than aerospace 2024, and easier to machine than 7075. The trade-off is limited corrosion resistance and no weldability, which means it fits indoor, machined-component applications best.<\/p>\n Linsy Aluminum supplies 2017 in plate, bar, and tube, with custom dimensions available at low minimum order quantities. MTC documentation is included with every order, and SGS testing is available on request. Send the drawing for a grade-fit review.<\/p>\n 2024 has higher strength (~470 MPa UTS in T4 vs. 2017’s ~430 MPa) and better fatigue performance. 2017 is the more economical option \u2014 its strength is still well above 6061, and machinability is slightly better than 2024. The choice usually comes down to whether the extra strength margin of 2024 is worth the cost.<\/p>\n Not without cladding or protective coating. The copper content that gives 2017 its strength also makes it susceptible to galvanic corrosion in saltwater. For marine applications, 5083, 5086, or 6061 with appropriate surface treatment are better choices.<\/p>\n It machines well with standard aluminum tooling, but surface speed should be checked against the T4 temper response. Chip evacuation is generally good, and built-up edge is less of an issue than with gummier 5000-series alloys. Coolant is recommended for high-volume runs to control thermal expansion.<\/p>\n Standard plate and bar forms are more common, but sheet may be available depending on the temper and thickness. Contact the supplier with the specific gauge and temper requirement to check current stock or custom production lead times.<\/p>\n MTC (Mill Test Certificate) documenting chemical composition and mechanical properties is standard for every order. Third-party SGS reports for chemical composition, mechanical properties, and dimensional inspection are available on request at additional cost.<\/p>","protected":false},"excerpt":{"rendered":" Introduction 2017 aluminum alloy \u2014 historically known as duralumin \u2014 is one of the earliest high-strength aluminum alloys.
