Developing Trend for Aluminium Fasteners

 Aerospace fastener demand:

Fasteners are small parts, but they are an indispensable key component to support and connect the entire aircraft. According to Boeing and Airbus' forecast, the global aircraft demand in the next 20 years will exceed 40,000 aircraft, which even does not include military airplanes and helicopters. There are millions of fasteners on each aircraft. In terms of aluminum fastener sizes, aerospace fasteners with a diameter of less than 32mm can generally be produced in large quantities using aluminum wire. However, the large-size aerospace fasteners that are used on aircraft interiors and even on air cargo containers can be produced by aluminum extruded straight or hexagonal bar.

                                      
The future trend of fastener market:

-Lightweight design of aerospace fasteners: Corresponding to the trend of energy saving, carbon emissions reduction, and consolidating the competitiveness of airline companies, Lightweight aircraft design has become the mainstream trend in the aviation industry, and the fastener is definitely one of the main items of lightweight design. In addition to lightweight design, the strength of the fastener itself must conform to aeronautical safety standards as well. Therefore, the demand for lightweight designs in high-strength aluminum fasteners is about to see a boom in the future.

 
-Application of automotive fasteners: Nowadays, it’s an inevitable trend to reduce the weight of vehicles. Not only the frame, body sheet metal, and chassis are all developing toward lightweight designs, but also the high-end models are aluminum alloyed for engines and transmissions. Therefore, expanding the aluminum fastener market is also the mainstream trend at this moment for the automotive market.

The specifications of Aerospace Fasteners in the current market:

   -Alloy type: mainly in 7050, 7075, 2024 series

   -Produced by straight/ hexagonal bar: 6mm to 63.5mm in diameter (30% of the total demand)

   -Produced by wire: 2mm to 25.4mm in diameter (70% of the total demand)

 
Ye Fong Hot-Rolled aluminum wire / rod:

-               Production method: Hot Rolled Type

-               Weight: around 600lb (300kg) per coil

-               Alloy: 7075, 7050, 2024, 2014, 2017, 2117, 6061, 6056, 5056, 6082, etc.

-               Condition: O /H/ T

-               Redraw Rod (Ø 8~32mm) for forging and drawing

-               Finished Wire (Ø 4~30mm) for cold heading, fasteners and rivets

-               Features: Fine Grain Size Structure / Better Formability & Machinability & Superior Surface Quality

-               Application: Aerospace fasteners / Automotive fasteners

 

The aluminum wire from Ye Fong is hot-rolled type instead of a cast-rolled type. The highest application of fasteners manufactured by cast-rolling can only be used for automotive, and cannot be used for aerospace. However, the aluminum wire produced by hot-rolled method completely solves the problem of surface segregation layer impurities and non-uniformity grain structure. This is achieved through Ye Fong peeling, shaving, hot rolling, homogenization treatment, on-line eddy current test and other manufacturing processes. It also provides fastener manufacturers with better machinability & formability, meeting the demand of the aerospace and automotive fastener markets at the same time.

With our special hot rolling technology we can process a wide range of sizes and alloys, delivering fine grained structures with excellent formability at a competitive price. Main end use markets are aerospace, automotive, and general engineering industries.

Exclusive Technology to Manufacture Hot Rolled Wire for Aerospace Fasteners 
 Ye Fong now specifically supplies aluminium alloy materials for aerospace screws, nuts, small rivets and other fasteners in various diameters. This type of material is in short supply due to the scarcity of its makers. Rivets are made of hot rolled wires and currently only 2 companies in the world can manufacture those wires made of high-strength aluminium alloy. One of them can only provide 200kg per coil. The other, which is Ye Fong, has come up with an exclusive technology to be the world's first supplier to provide 300kg per coil.

Materials for aircraft interior components, such as aircraft seating system or hydraulic tube, are the current top seller of Ye Fong. For many years the company has produced a large amount of aluminium components for aircrafts and mainly supplies to Northern America and Europe. 

Expert of Aerospace Fastener Materials
Aerospace fasteners are made of hot-rolled aluminium alloy wire rods. A Boeing 747 aircraft users more than 2 million fasteners and therefore needs a large amount of material. The wires Ye Fong produces for fasteners ranging from 2mm up to 32mm can cover all the usage demand for fasteners. These wires per coil weight 300kg without welding, which is an exclusive advantage to Ye Fong. It indeed saves a lot of cost for customers on time-changing and labor cost.Ye Fong services some of the large corporations such as Arconic, PCC and Titanium through which its products are supplied to the U.S. and Europe. 

Aerospace fasteners are mostly made of wire rods and sometimes straight bars. Wire rods are mostly made by continuous high speed forging and therefore reduce cost.  On the other hand, straight bars are made by CNC processing and therefore its production is slower. To be accepted into the aerospace market, wire rods must be in a flawless state by shaving the surface of the aluminium wires as an additional process. It is very easy to peel titanium, steel and copper wires, but shaving aluminium alloy is extremely difficult.  After a year of research and improvement, we are finally develop the technology to shave aluminium alloy successfully.
