Definitions
- the invention relates to the use of a low-alloy phosphorus deoxidized Copper alloy for the production of hollow profile components by internal high pressure forming according to the features of claim 1 and one from the Hollow section component made of copper alloy.
- Internal hydroforming is understood to mean processes in which tubular Workpieces or hollow profiles are formed with active media support.
- improved properties can be manufactured with high precision using other methods would not be possible or could only be realized with much higher effort.
- suitable components and Materials especially the knowledge of the process control limits of importance. For example, an internal pressure that is too low and one that is applied at the same time Too much displacement of the pipe ends to unfold or kink the Workpiece lead, whereas a strong internal pressure with too little Pushing the pipe ends results in failure due to tearing or bursting can pull.
- the object of the invention is for use in hydroforming for the production of hollow profile components to show low-alloy phosphorus-deoxidized copper alloy, which in the undeformed Condition has an increased yield strength and an increased tendency to harden already at low degrees of deformation.
- Another object of the invention is to achieve a high pressure forming to show manufactured hollow profile component with improved material properties.
- the invention solves the procedural part of the task through the use a low alloy phosphorus deoxidized copper alloy (Cu-DHP) with the Features of claim 1.
- the copper alloy is 0.030 to 0.080% by weight of at least one element made of tin (Sn), zinc (Zn), iron (Fe) and silver (Ag) existing group as well as the by standardization prescribed phosphorus content of 0.015 to 0.040 wt .-%, and at least 99.90% by weight copper and the remainder unavoidable impurities.
- the elements tin and zinc are preferably used, in particular in Proportions of 0.030 to 0.050 wt .-%, preferably tin with a mass fraction of 0.050% by weight (claims 2 and 3). Also additions of silver in the The order of magnitude of 0.008 to 0.010% by weight (claim 4) also leads to one Increasing the yield strength or the 0.2% proof stress. It is the same with an alloy of silver with a mass fraction of 0.002 to 0.007% by weight and at the same time iron with a mass fraction of 0.005 to 0.010% by weight (Claim 5).
- Residual weight fractions include the sum of As, Bi, Cd, Co, Cr, Mn, Ni, O, Pb, S, Sb, Se, Si and Te.
- a phosphorus-deoxidized is particularly advantageous Copper alloy with a weight fraction of 99.90% to 99.95% copper considered with addition of tin in the order of 0.030 to 0.050% by weight, in particular 0.050% by weight.
- the objective part of the task is a profile component according to the Features of claim 6 solved. This is made from a DHP copper Prepared composition described above, especially in one Tin content from 0.030 to 0.050% by weight.
- the hollow profile component is preferably a piece of pipe with at least one branch, especially a T-piece.
