The landing gear is one of the essential parts of an aircraft. It’s also one of the hardest to make. So, how does a landing gear get made?
A toughmet starts by being formed from steel sheets in a rolling mill. Once it’s created, it goes through many processes, including cutting and punching holes for rivets or bolts before being sent off to be heat-treated at high temperatures and tempered.
What Are The Benefits Of Toughmet?
The benefits include: wear resistance; strength to weight ratio; good thermal conductivity; low electrical resistivity at room temperature; oxidation stability up to 1800°F (9800C); nonmagnetic properties above 1000°F(5400C). Other advantages are its ability to retain form after forming or stamping processes and its resistance to acids and alkalis.
What Are The Applications For Toughmet?
Toughmet is used for various applications, including high-end turbocharger blades, jet engine combustion chamber components, aircraft turbine shrouds, combustor liners, and stationary nozzles, as well as gas turbines such as the Rolls Royce Trent 1000 (used in Boeing’s Dreamliner).
It can also be found in oilfield service pumps involved with enhanced oil recovery methods like waterflooding or steam flooding. Other uses include wearing plates where hardness combined with toughness is essential, electrical contacts which require good heat transfer properties, and resistance to oxidation at elevated temperatures.
How Is It Made?
The process begins with arc melting, where the metal is melted using an electric arc between a consumable tungsten electrode and the raw material to be refined. This requires much less energy than melting with a furnace for either induction or resistance heating methods. The molten alloy is then poured into ingot molds that are cooled down in the water. This process does not require any additives to create taught. It can meet high purity standards (>99%).
This stainless steel grade has exceptional toughness combined with high strength properties due to its copper-beryllium content, making it suitable for heavy-duty applications. It also offers good corrosion resistance compared to other nickel-based superalloys making it ideal for use in harsh environments such as seawater, gas turbines, steam turbine blades, and oil and gas extraction.
Toughmet As Compared To Other High-Performance Alloys
The advantages of Toughmet are its very high strength combined with excellent toughness and corrosion resistance.
The alloy can be used in demanding applications where components need to withstand severe conditions such as high pressure (fracture mechanics), elevated or low temperatures (creep), or simultaneously, like gas turbines. For this reason, it is gaining increased interest among manufacturers of turbomachinery components.
- Good weldability;
- High yield strength after heat treatment (>20 HRC)
- Excellent formability
- Excellent creep properties at continuous service temperature up to 650°C combined with relatively low hardness values (<35 HRC);
- High Strength And Corrosion Resistance Combined With Low Density And Exceptional Machinability: – Toughmet has a yield strength of more than 20 HRC and good cold form-ability
What Is The Chemical Composition Of Toughmet?
Toughmet contains approximately 70% Copper, 25 – 30% Beryllium, up to 0.05 % Iron, and small amounts of other elements depending on grade (e.g., Titanium, Molybdenum).
We want to conclude that thought is a low-cost alternative to titanium alloys, with similar strength and corrosion resistance. It can be used in many different industries such as Aerospace, Oil & Gas, or Marine Industries, where its weight-saving properties will give customers an edge over competitors.
