         2 . The alloy as claimed in  claim 1 , wherein the other chemical elements have contents by weight of the order of or less than 0.1%.  
     
     
         3 . The alloy as claimed in  claim 2 , containing around 4.5 wt % aluminum, around 4 wt % nickel, around 2 wt % iron, around 0.5 wt % silicon, around 0.3 wt % manganese and around 0.1 wt % tin.  
     
     
         4 . A sensor for measuring at least one physical parameter, such as temperature, pressure, flow rate, velocity, impact, which includes at least one component made of an alloy as claimed in one of the preceding claims.  
     
     
         5 . A sensor provided with thermal deicing means for measuring at least one physical parameter on a stream of fluid, which includes at least one component made of an alloy as claimed in one of  claims 1  to  3 .  
     
     
         6 . A sensor for measuring physical parameters at the inlet of an engine or on the outside of an aircraft, which includes at least one component made of an alloy as claimed in one of  claims 1  to  3 .  
     
     
         7 . A process for producing a component made of an alloy as claimed in one of  claims 1  to  3 , wherein a foundry treatment is carried out.  
     
     
         8 . The process as claimed in  claim 7 , wherein the foundry treatment is a crude foundry treatment.  
     
     
         9 . The process as claimed in  claim 7 , wherein the foundry treatment is a foundry treatment with a heat treatment.  
     
     
         10 . The process as claimed in  claim 9 , wherein the heat treatments are followed by forming treatments.  
     
     
         11 . The process as claimed in  claim 7 , wherein the foundry treatment is immediately followed by forming operations.  
     
     
         12 . A process for producing a component made of an alloy as claimed in one of  claims 1  to  3 , wherein a sintering treatment is carried out.
