Metal Materials & Products

This category includes a range of metals such as steel, aluminum and others, in different alloys and tempers, used for manufacturing products in different forms (sheets and plates, bars/rods, tubes, wires, etc.). They are widely encountered in aerospace, automotive and many other industrial sectors. Alloys are created by adding small amounts of metallic elements into the base metals to improve their characteristics. These “alloying” elements allow a base metal to improve its attributes and better respond to the requirements of specific applications. Alloy metals an be classified in a variety of different ways depending on their composition (e.g. carbon, low-alloy or stainless steel, in the case of steels), manufacturing methods, finishing method (such as hot rolling or cold rolling), product form (bar,sheet, tube, etc), heat treatment (such as annealing, quenching and tempering), required strength level  as specified in ASTM standards) and others. Because of the wide variety of chemical compositions possible and the fact that some steels are used in more than one heat-treated, condition, some overlap exists among the alloy steel classifications. 

In the case of aluminum alloys, each alloy has attributes such as high strength, conductivity, and even resistance to environmental effects.  A naming system using four-digit designators has been developed by the US Aluminum Association, to organize them. The first digit represents the specific alloying elements and general characteristics of the group, or the “series”.

In selecting an alloy, its mechanical properties should be carefully considered. The mechanical properties of different alloys differ based on how they are heat treated, or made stronger using the tempering process.

Some important measures when considering mechanical properties include the yield strength, ultimate strength, shear strength, fatigue strength, as well as the modulus of elasticity and shear modulus. The yield strength describes the maximum amount of stress needed to elastically deform the part in a given loading arrangement (tension, compression, twisting, etc.). The ultimate strength, on the other hand, describes the maximum amount of stress a material can withstand before fracturing. Before the fracture point, the material will undergo plastic (or permanent) deformation, and will not return to its original shape. For static applications, the yield strength is the more important design constraint as per industry standard design practices; however, the ultimate strength can be useful for certain applications where this kind of deformation is possible. The shear strength measures the maximum amount of “shearing” stress that a material can experience before it permanently deforms. Fatigue strength is the ability of a material to resist breaking under cyclical loading, where a small load is repeatedly imparted on the material over time. This value is useful for applications where a part is subject to repetitive loading cycles such as vehicle axles or pistons. The modulus of elasticity and shear modulus are measures of a material’s resistance to deformation.

Sourced from quality producrs, a wide range of metals are offered, most of them as part of our own branded (AVIATIONEU NEW ERA) product lines. They are available in pre-cut dimensions or cut-to-oder, meeting different specifications and in diferent units of sale, (pieces or tons) depending on the wanted order quantity and requirements. Please refer to the respective sub-categories and the individual product presentations for additional information.

  • Mfr. P/N & Title: 4130 Alloy Steel Round Rod/Bar Cold Finished Normalized Dia (in.) 1.875/3FT

AVIATIONEU NEW ERA 4130...

Steel alloy 4130 (ST4130),aka Chrome Moly,after the 2 key composition elements,chromium & molybdenum,is a general-purpose alloy steel widely used by the aviation and motorsports industries due to its weldability, fabrication and mild hardenability in all offered forms (tubes, bars/rods, sheets and plates). Available in two material states (Normalized and Annealed) depending on the process of how the material is heated and cooled.The Normalized condition (aka "Condition N") is the harder and stronger condition, best used when forming is not needed while the Annealed condition (aka "Condition A") is the softer and formable condition.

4130 steel bars/rods in round, rectangullar (flat), square and hexagonal shapes (cross sections) are offered as part of our own branded (AVIATIONEU NEW ERA) product lines. Sourced from quality producers, most of these bars/rods are produced, unless otherwise specified, as “Cold Finished Normalized” (aka “Condition D4”), indicated by the letters "NRZ" and  "CF" in the product SKUs. They come in different dimesions in inches and cut to order (CTO) lengths in feet (*) and meet several AMS specifications, most common being AMS-S-6758 and AMS- 6348. They are widely used in a variety of applications due to their excellent strength to weight ratio,weldability by all conventional methods and resistance to scaling and oxidation. 

Unless otherwise mentioned, there is additional cost if manufacturing test reports are required. For additional information, please refer to the supplied documentation, the individual product presentations or contact us.

(*) As per vendors' requirements, certain 4130 steel bars/rods are ONLY SOLD in 3 feet increments, i.e. cut lengths can only be set to 3, 6, 9 feet etc. as mentioned in the respectivel product presentations. In this case, appearing prices are per 3 feet length and the Minimum Order Quantity (MOQ) is 3 pieces for each of selected rod/bar. Required cut lengths should be specified at the time of ordering.
