The copper tube is a silenced and drawn seamless tube. Light
weight, good thermal conductivity, high temperature.
Used to make heat transfer equipment (such as condenser, etc.). It
is also used in oxygen - making equipment to assemble cryogenic
piping. Small diameter copper tubes are often used to transport
pressurized liquids (such as lubricating systems, oil pressure
systems, etc.) and pressure gauges for instrumentation. The quality
of copper tube is very stable.
H65 is an alloy of copper and zinc. When the zinc content is less than 39%, zinc can be dissolved in
copper to form single-phase a, called single-phase brass, good
plasticity, suitable for hot and cold pressure processing. When the zinc content is greater than 39%, there is a single phase
and b solid solution based on copper and zinc, called biphase
brass, b makes plastic small and tensile strength rises, only
suitable for hot pressure processing if continue to increase the
mass fraction of zinc, tensile strength decreases, no use value
code with "H + number", H represents brass, The number represents the mass fraction of copper. For example, H68 means brass with 68% copper and 32% zinc, while
cast brass has a "Z" in front of the code, such as ZH62 or Zcuzn38
means cast brass with 38% zinc and a margin of copper. H90, H80 single-phase, gold, so there is a gold common name, called
coating, decoration, medal, etc. H68, H59 belong to biphase brass, widely used in electrical
structures, such as bolts, nuts, washers, springs and so on. In general, single-phase brass is used in cold deformation
processing and biphase brass is used in hot deformation processing.
