1. acupuncture needle suppliers Acupuncture needles are typically made of stainless steel wire. They are usually disposable, but reusable needles are sometimes used as well, though they must be sterilized between uses.Needles vary in length between 13 to 130 millimetres (0.51 to 5.1 in), with shorter needles used near the face and eyes, and longer needles in more fleshy areas; needle diameters vary from 0.16 mm (0.006 in) to 0.46 mm (0.018 in),with thicker needles used on more robust patients. Thinner needles may be flexible and require tubes for insertion. The tip of the needle should not be made too sharp to prevent breakage, although blunt needles cause more pain. Apart from the usual filiform needle, there are also other needle types which can be utilized, such as three-edged needles and the Nine Ancient Needles.Japanese acupuncturists use extremely thin needles that are used superficially, sometimes without penetrating the skin, and surrounded by a guide tube (a technique adopted in China and the West). Korean acupuncture uses copper needles and has a greater focus on the hand 2. straight steel wire Steel wire armoured cable, commonly abbreviated as SWA, is a hard-wearing power cable designed for the supply of mains electricity. It is one of a number of armoured electrical cables which include 11kV Cable and 33kV Cable and is found in underground systems, power networks and cable ducting. 3. stainless nonmetallic wire 4. traditional acupuncture needle Acupuncture is an alternative medicine methodology originating in ancient China that treats patients by manipulating thin, solid needles that have been inserted into acupuncture points in the skin. According to Traditional Chinese medicine, stimulating these points can correct imbalances in the flow of qi through channels known as meridians. Scientific research has not found any histological or physiological correlates for qi, meridians and acupuncture points, and some contemporary practitioners needle the body without using the traditional theoretical framework. Current scientific research indicates that traditional forms of acupuncture are more effective than placebos in the relief of certain types of pain and post-operative nausea. Other reviews have concluded that positive results reported for acupuncture are too small to be of clinical relevance and may be the result of inadequate experimental blinding, or can be explained by placebo effects and publication bias. 5. wire for shaft pin 6. steel spring wire 7. stainless steel spring wire 8. stainless steel wire brush In metallurgy, stainless steel, also known as inox steel or inox from French "inoxydable", is defined as a steel alloy with a minimum of 10.5% to 11% chromium content by mass. Stainless steel does not readily corrode, rust or stain with water as ordinary steel does, but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity, or poor circulation environments. It is also called corrosion-resistant steel or CRES when the alloy type and grade are not detailed, particularly in the aviation industry. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and resistance to corrosion are required. Stainless steel differs from carbon steel by the amount of chromium present. Unprotected carbon steel rusts readily when exposed to air and moisture. This iron oxide film (the rust) is active and accelerates corrosion by forming more iron oxide, and due to the dissimilar size of the iron and iron oxide molecules (iron oxide is larger) these tend to flake and fall away. Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion and blocks corrosion from spreading into the metal's internal structure, and due to the similar size of the steel and oxide molecules they bond very strongly and remain attached to the surface. Passivation only occurs if the proportion of chromium is high enough and oxygen is present. 9. stainless spring wire 10. stainless wire brush 11. stainless cotter pins A cotter is a pin or wedge passing through a hole to fix parts tightly together. In British usage cotter pin has the same meaning, but in the U.S. it refers to a different fastener. Typical applications are in fixing a crank to its crankshaft, as in a bicycle, or a piston rod to a crosshead, as in a steam engine. Note: the angle of the wedge determines the position of the parts being held, therefore on a bicycle the pedal arms will only be at 180 degrees to each other if the angle of the cotter pin's wedge is the same on both pins. 12. stainless steel linch pins A linchpin, also spelled linch pin, lynchpin, or lynch pin, is a fastener used to prevent a wheel or other part from sliding off the axle upon which it is riding. The word is first attested in the 14th century and derives from Middle English elements meaning "axletree pin". Securing implements onto the three-point hitch of a tractor is an example of application. Linchpins may also be used in place of an R-clip for securing hitch pins.[citation needed] The word "linchpin" is also used figuratively to mean "something [or someone] that holds the various elements of a complicated structure together."
