What is LM series in aluminium?
‘LM’ prefix being a standard code to reflect the chemical composition and varying proportions of the different trace metals. LM6 : LM6 is a corrosion resistant aluminum casting alloy with average durability and strength, and with high impact strength and ductility.
What is LM9?
LM9 alloy is used where the fluidity and corrosion resistance of LM6 are required with high strength and hardness. It is equally suitable for sand and permanent mould casting and is extensively used for low pressure castings. LM9.
What is the fatigue strength for the 2024 aluminum?
138 MPa
The fatigue strength is the measure of how resistant a material is to breaking under such fatigue, and the fatigue strength for 2024 aluminum is 138 MPa (20,000 psi), calculated with 500,000,000 cycles of loading under the yield point.
What is LM 25 in aluminium?
LM25 – Aluminium Casting Alloy LM25 is a common general purpose alloy of aluminium which is used where good mechanical properties are needed. It has a good resistance to corrosion and has high strength. It responds well to heat treatment and is available in four different conditions.
What is lm material?
LM bearings are made from machined bronze semicast material. Alloy is Rg7 (CC493K, red bronze). The bearing are produced in acc.
What is LM4 Aluminium?
(Al – Si5Cu3) This alloy conforms with British Standards 1490 LM4 and is similar to the obsolete specifications BS. L79 and D.T.D 424A. Castings may be in the cast (M) of fully heat treated (TF) conditions.
Where is AlSi10Mg used?
AlSi10Mg is an age-hardening cast aluminum alloy with good hardness, strength and dynamic toughness. It is traditionally used as a casting alloy. Powder made from AlSi10Mg is commonly used in additive manufacturing, due to the high corrosion resistance, low density and high mechanical strength of the final components.
What material is AlSi10Mg?
aluminum-
AlSi10Mg is a hardenable aluminum- based alloy with a density of circa 2.67 g/cm³ [2]. It is applicable for thin-walled components and parts with complex geometries. AlSi10Mg is highly suitable for processing and characterized by a good resistance in corrosive atmospheres as well as a high electrical conductivity.
What is the composition of Aluminium alloy?
An Aluminium alloy (or aluminum alloy; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc.
What is LM25 alloy?
LM25 is mainly used where good mechanical properties are required in castings of shape or dimensions requiring an alloy of excellent castability in order to achieve the desired standard of soundness.
How is AlSi10Mg made?
AlSi10Mg specimens were produced by the SLM technique from gas atomized pre-alloyed powders. The study shows the distinctive layered macrostructure, and the extremely fine cellular dendritic microstructure obtained by the SLM AM process, along with the remarkable tensile testing results for AlSi10Mg components.
What do aluminum alloy numbers mean?
Each alloy is given a four-digit number, where the first digit indicates the major alloying elements, the second — if different from 0 — indicates a variation of the alloy, and the third and fourth digits identify the specific alloy in the series.
How do you read aluminum alloys?
The wrought aluminum series names elements with four numerical digits where the first digit represents the principal alloying element, the second digit indicates a modification of a specific alloy, and the third and fourth digits are arbitrary numbers assigned to specific alloys in the series.
