Aluminium alloys are often used due to their high strength-to-weight ratio, corrosion resistance, low cost, high thermal and electrical conductivity.There are a variety of techniques to join aluminium including mechanical fasteners, welding, adhesive bonding, brazing, soldering and friction stir welding (FSW), etc. Various techniques are used based on the cost and strength required for the joint.
Free-flowing, most fluid of aluminium filler metals. General purpose filler metal, can be used with brazeable aluminiums in all types of brazing. For joining aluminium and its alloys. Can be used for joining aluminium and titanium to dissimilar metals; the risk of galvanic corrosion then has to be considered.
Brazing practice. Brazing is a metal-joining process in which two or more metal items are joined by melting and flowing a filler metal into the joint, with the filler metal having a lower melting point than the adjoining metal. Brazing differs from welding in that it does not involve melting the work
An amorphous brazing foil (ABF) is a form of eutectic amorphous metal that serves as a filler metal in brazing operations. ABFs are composed of various transition metals (including nickel, iron, and copper) blended with metalloids like silicon, boron, and phosphorus.
A rear view of the original iPhone (left) made of aluminum and plastic, and the iPhone 3G (right) made entirely from a hard plastic material [21] The iPhone 3G's back featured a redesigned polycarbonate plastic housing, replacing the aluminum back of the first generation. Buttons were changed from plastic to metal, and the edges of the phone ...
Type 2 photosensitive anodized aluminum is typically coated with a photo resist, which may be of either the positive or negative type. Exposure of the photo resist through a negative and its subsequent development creates areas on the plate that are either protected by the resist or exposed to the effects of the dye, bleach, or etchant that are ...
Video over cellular (VoC), also known as VoCIP (video over cellular Internet Protocol), is a term used for processing streaming video such as surveillance, using high-resolution video cameras over 3G and 4G cellular networks. Creating a VoC transmission requires encoding and decoding of video packets
Brazing alloys are used for joining materials by brazing. Care has to be taken while choosing the alloys, as some elements tend to outgas. Cadmium and zinc are the worst common offenders. Silver, a common component of brazing alloys, can be problematic at higher temperatures and lower pressures.
