What no one tells you about aluminum framed outdoor furniture

图片
Most outdoor furniture is constructed with aluminum frames. The frames are made of extruded aluminum tubes of different shapes and sizes, reinforced by internal support walls, creating a very strong and structurally robust, durable, resilient frame. Most hollow aluminum tubes undergo a process called extrusion. Extrusion is a method of forming a material, such as aluminum, by forcing the material to flow through a forming opening in a die. The formed material emerges as a long tube or other shape included with the contours of the die. Extruded aluminum is characterized by its uniformly smooth, perfect surface and can be made into very complex and precise shapes. It can be cut, welded, bent and machined for further production. Quite simply, this means that a piece of metal is forced through a machine that shapes it into a hollow, round or square shape.   For designers and engineers, the possibilities are endless when designing with aluminum extrusions.  Aluminum extrusions can provide s

Introduction of Extruded Aluminum

Extruded aluminum is a continuous item of lightweight aluminum, generally with a consistent profile or cross-section over its entire length. It is made forcibly a block of lightweight aluminum, called a billet, through a die opening that is smaller than the initial cross-sectional location of the billet. The extrusion procedure can be warm or cold, depending upon the type of lightweight aluminum alloy as well as the extrusion technique made use of. Lightweight aluminum is an excellent material because it is lightweight, solid as well as rust-resistant. In its pure kind, it is soft as well as has low strength. To boost its mechanical properties, it is normally alloyed with aspects such as copper, magnesium, manganese, and also silicon. Additionally, it can be warmly treated to additional boost strength as well as ductility as well as to achieve the appropriate equilibrium. Lightweight aluminum is the most generally used metal  for extrusion molding. This steel has a one-of-a-kind mix of

Design factors that affect the thermal performance of a heat sink

When selecting or designing a heat sink, the following factors must be considered. Material The most common heat sink material is aluminum alloy. Aluminum alloy 1050A has one of the higher thermal conductivity values, 229 W/m•K, but is mechanically soft. Aluminum alloys 6060 and 6063 are commonly used and have thermal conductivity values of 166 and 201 W/m•K, respectively. These values depend on the temper of the alloy.   Heat sink efficiency The heat sink fin can be thought of as a flat plate where heat flows at one end and is dissipated into the surrounding fluid as it travels to the other end. As heat flows through the fins, the thermal resistance of the heat sink that impedes the flow and the heat loss due to convection combine to reduce the temperature of the fins and therefore the  heat transferred to the fluid from the bottom to the end of the fins .   Thermal resistance The heat flow between the semiconductor chip and the ambient air is modeled as a series of thermal flow resis

How to make aluminum trim

What are aluminum trim pieces? Aluminum is a very common specified material used for extrusions and formed profiles that can be made into long, narrow, flexible and adaptable pieces for architectural trim applications and accents, interior and exterior lighting, and engineering design. The use of aluminum trim pieces stems from the many positive properties of aluminum; these include its resistance to rust and corrosion and its low density.   Advantages of aluminum extrusion. Extrusion has proven to be the most efficient and effective method of producing aluminum trim, as it is both economical and provides immediate results. Aluminum's high ductility means that the metal can be easily formed into a variety of cross-sections without the need to expend a lot of energy in the tooling or forming process, and aluminum also typically has a melting point that is about half that of ordinary steel. These two facts mean that the aluminum extrusion process has a relatively low energy footprint
