  • World's strongest aluminum alloy
    A new patent-pending aluminum alloy from Kobe Steel is made using a spray forming process and is said to be the strongest aluminum alloy available. It has a tensile strength of 780 MPa. That's reportedly 10% higher than the 710 MPa of Weldalite, an aluminum-lithium alloy developed by and used
  • Fatigue Life Improvement Of An Aluminum Alloy Fsw With Low Plasticity Burnishing (.pdf)
    Friction stir welding provides a new. technology for solid state joining of a wide. variety of aluminum alloys that cannot be. joined with conventional fusion welds. However, recent work has shown that. significant tensile residual stresses are. developed in the stirred region with local. tension
  • Aluminum-Alloy Bearings
    Aluminum bearing alloys have wear resistance, high load-carrying capacity, fatigue strength, thermal conductivity, and excellent corrosion resistance, and low cost. They are used extensively in connecting-rod and main bearings in internal combustion engines, hydraulic gear pumps, oil-well pumping
  • Fatigue Life Improvement and Mitigation of Pitting Corrosion Damage of Friction Stir Welded 2219-T8751 Aluminum Alloy by Low Plasticity Burnishing (.pdf)
    Friction stir welding (FSW) is a new solid state joining process for aluminum alloys including those alloys considered not weldable. However, the FSW process produces zones of tensile residual stress at the edges of the stir zone. Recent residual stress studies performed at Lambda Research
  • Aluminum
    Though light in weight, commercially pure aluminum has a tensile strength of about 13,000 psi. Cold working the metal approximately doubles its strength. In other attempts to increase strength, aluminum is alloyed with elements such as manganese, silicon, copper, magnesium, or zinc. The alloys can
  • "Brick Wall " Helps Explain How Corrosion Spreads Through Alloy
    new insights into how microscopic corrosion attacks an aluminum alloy commonly used in aircraft. They 've developed a statistical model of the deterioration and simulated it on computer, using what may seem like an unlikely analogy: a cracking brick wall. What they 've found could one day help
  • Alloy Steel
    alloy steels: aluminum, chromium (to 3.99%), cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium, zirconium or other element added to obtain an alloying effect. Technically, then, tool and stainless steels are alloy steels. In this chapter, however, the term alloy steel is reserved
  • Characterization of Tensile Residual Stresses in 7050-T7651 Aluminum Friction Stir Welds (.pdf)
    Salt spray corrosion pits are a common site of fatigue crack initiation in aluminum alloy aircraft components. Salt corrosion pitting occurs during exposure to the marine atmosphere and results in intergranular corrosion to a depth dependent on the time of exposure, temperature, and the service
  • The Effect of Surface Enhancement on the Corrosion Properties, Fatigue Strength, and Degradation of Aircraft Aluminum (.pdf)
    . The corrosion fatigue and pitting corrosion performance of 7475-T7351 aluminum. alloy is investigated for both SP and LPB treated test specimens. In all cases,. LPB provided greater resistance to pitting and SCC damage. Corrosion fatigue. life and damage tolerance were improved compared to the SP
  • Bronze and Copper-Alloy Bearings
    Dozens of copper alloys are available as bearing materials. Most of these can be grouped into five classes: copper lead, copper tin (sometimes called tin bronze), leaded bronze, aluminum bronze, and beryllium copper. As a general rule in these alloys, a higher lead content promotes compatibility
  • X-ray Fluorescence for Aluminum Metals/Alloy Identification: Nitronic 60 Identified with an SDD, XPIN6 and XPIN13
    The questions being addressed is: "What is the best detector to use for aluminum metal and alloy identification, an SDD or a PIN detector?" This paper shows that both a XPIN6 and SPIN13 detector can identify aluminum alloys, though an SDD detector does have some advantages in identifying some
  • X-ray Fluorescence for Non-Aluminum Metals/Alloy Identification: Naval Brass Identified with an SDD, XPIN6 and XPIN13
    The question being addressed is: "What is the best detector to use for non-aluminum metal and alloy identification, an SDD or a PIN detector?" This paper shows that both a PIN and a SDD detector are equally adequate for identifying many common non-aluminum metals and alloys. The results section

  • Diamond Plate Aluminum Restoration
    Walking downtown we have all come across a piece of faded diamond plate, often times it is in extremely bad shape. Diamond plate aluminum is used for hatch covers and at crosswalks to prevent slips and falls for pedestrians but is a softer alloy by nature and may wear easily in high traffic
  • How to Avoid Cracking in Aluminum Alloys
    The majority of aluminum base alloys can be successfully arc welded without cracking related problems, however, using the most appropriate filler alloy and conducting the welding operation with an appropriately developed and tested welding procedure is significant to success
